## Summary of Changes
### Problem
When duplicating a project with an uploaded (non-Unsplash) background
image, users encounter an internal server error (HTTP 500). The backend
logs show: `file was not downloaded from unsplash [FileID: X]`
### Root Cause
The `duplicateProjectBackground` function in
`pkg/models/project_duplicate.go` uses named returns. When
`GetUnsplashPhotoByFileID` returns `ErrFileIsNotUnsplashFile` for an
uploaded background, the error was intentionally ignored (to proceed
with copying the file) but not cleared from the named return variable.
This caused the error to be returned at the end of the function via the
bare `return` statement, triggering a 500 response.
### Solution
Changed the bare `return` at the end of `duplicateProjectBackground` to
`return nil` explicitly.
### Changes
1. **`pkg/models/project_duplicate.go`**: Changed bare `return` to
`return nil` at the end of `duplicateProjectBackground`
2. **`pkg/models/project_duplicate_test.go`**: Added subtest "duplicate
project with uploaded background" to `TestProjectDuplicate`
### Testing
- All existing tests pass
- Added subtest to `TestProjectDuplicate` for uploaded background
scenario (project 35 with non-Unsplash background)
### Security Summary
- No security vulnerabilities found by CodeQL
- Code review passed

> # Duplicate project with uploaded background - Implementation Plan
>
> ## Overview
> Users encounter an internal server error when duplicating a project
that uses an uploaded background image (non-Unsplash). The b
> ackend attempt to copy the background leaves a non-Unsplash error
(`ErrFileIsNotUnsplashFile`) in a named return value, causing
> the duplication API call to fail even though the error should be
ignored. We need to adjust the duplication flow to allow upload
> ed backgrounds and add regression tests.
>
> ## Current State Analysis
> - Project duplication calls `duplicateProjectBackground` to copy the
background file. The helper tries to copy a downloaded Unsp
> lash image and returns `ErrFileIsNotUnsplashFile` for uploaded files.
> - In the duplication code, the error variable is not cleared after
intentionally ignoring this specific error, so the function s
> till returns the error and triggers a 500 response.
> - There are no automated regression tests covering project duplication
with uploaded backgrounds.
>
> ### Key Discoveries
> - The duplication logic treats Unsplash and uploaded backgrounds
differently and only clears the Unsplash download error, leavin
> g the non-Unsplash error set.
> - The API currently works for Unsplash backgrounds but fails for
uploaded backgrounds due to the lingering error value.
>
> ## Desired End State
> - Duplicating a project succeeds for both Unsplash and uploaded
backgrounds.
> - Uploaded background files (and their metadata) are copied correctly
to the new project when possible, or gracefully skipped wi
> thout failing duplication.
> - Regression tests cover duplication with both background types to
prevent future regressions.
>
> ## What We're NOT Doing
> - No changes to the background upload endpoints or UI selection
workflow.
> - No changes to Unsplash download behavior or quota handling.
> - No new migration or database schema changes.
>
> ## Implementation Approach
> 1. Fix backend duplication error handling so uploaded backgrounds do
not cause a fatal error.
> 2. Add backend tests to cover duplication with uploaded backgrounds
and Unsplash backgrounds (success paths) and verify duplicat
> ion works without returning 500 errors.
> 3. Ensure tests document the expected behavior and guard against
regressions.
>
> ## Phase 1: Fix duplication error handling
> ### Overview
> Make project duplication tolerate uploaded backgrounds by clearing or
not propagating `ErrFileIsNotUnsplashFile` once it has bee
> n intentionally ignored.
>
> ### Changes Required
> - **File:** `pkg/models/projects.go` (or relevant duplication helper)
> - Adjust `duplicateProjectBackground` (or the calling logic) to reset
the named return error after handling `ErrFileIsNotUnspl
> ashFile`, ensuring the function returns `nil` when no real error
occurs.
> - Keep existing behavior for other errors and for Unsplash downloads.
>
> ### Success Criteria
> - Uploaded background duplication no longer returns an internal server
error.
> - Unsplash background duplication remains functional and still
surfaces real errors.
>
> ## Phase 2: Add regression tests
> ### Overview
> Add automated tests verifying project duplication works for both
uploaded and Unsplash backgrounds.
>
> ### Changes Required
> - **File:** `pkg/models/projects_test.go` (or closest existing test
file for project duplication)
> - Add a test that sets up a project with an uploaded background file,
duplicates the project, and asserts duplication succeeds
> and the duplicated project has an appropriate background reference.
> - Add/adjust test coverage for Unsplash background duplication to
confirm unchanged behavior.
> - Use existing fixtures or temporary files as needed for uploaded
background setup.
>
> ### Success Criteria
> - Tests fail on current main branch but pass after the fix.
> - Tests validate that duplication completes without 500 errors for
both background types.
>
> ## Testing Strategy
> - Automated Go tests via `mage test:filter` targeting the new
duplication tests.
> - Optionally run the broader suite (`mage test:feature`) if time
permits to ensure no regressions.
>
> ## Manual Verification
> 1. Create a project and upload a background via the UI; duplicate it;
observe duplication succeeds and background is present or
> gracefully handled.
> 2. Create a project with an Unsplash background; duplicate it; verify
duplication succeeds.
> 3. Check API responses for duplication calls to ensure no internal
server errors.

This change fixes a few issues with the TickTick import:
1. BOM (Byte Order Mark) Handling: Added stripBOM() function to properly handle UTF-8 BOM at the beginning of CSV files
2. Multi-line Status Section: Updated header detection to handle the multi-line status description in real TickTick exports
3. CSV Parser Configuration: Made the CSV parser more lenient with variable field counts and quote handling
4. Test Infrastructure: Added missing logger initialization for tests
5. Field Mapping: Fixed the core issue where CSV fields weren't being mapped to struct fields correctly
The main problem was in the newLineSkipDecoder function where:
- Header detection calculated line skip count on BOM-stripped content
- CSV decoder was also stripping BOM and applying the same skip count
- This caused inconsistent positioning and empty field mapping
Rewrote the decoder to use a scanner-based approach with consistent BOM handling.

This fixes a panic that occurred when handling webhooks. The code was
incorrectly using webhook.CreatedByID (user ID) to fetch a project,
when it should use webhook.ProjectID. This could cause GetProjectSimpleByID
to return nil if no project exists with that ID.
Additionally, added a nil check before calling project.ReadOne() to prevent
a nil pointer dereference panic when accessing p.ID.

The filter_include_nulls property from the filter in a view would override the property set through the query string. Because we don't have a way in the UI to set this for filters in views, this makes the setting pretty opaque and unpredictable. Since we want to remove the nulls option anyways, we can just ignore it here.

When user names contain @ symbols, the email library fails to parse
the sender address format "Name @ Symbol via Vikunja <email@domain.com>".
This fix uses Go's net/mail.Address to properly format the sender
address according to RFC 5322, which automatically quotes names
containing special characters.
Fixes the error: "getting sender address: no FROM address set"
The filter regex pattern was not matching values inside parentheses correctly.
The lookahead pattern only allowed `&&`, `||`, or end-of-string after filter
values, but when filters are wrapped in parentheses like `( project = Filtertest )`,
the closing `)` appears after the value.
Fixed by adding `\)` to the lookahead pattern so it correctly handles closing
parentheses. This allows the project filter (and other filters) to work
properly when nested in parentheses.
- Added tests for project filters in parentheses (both frontend and backend)
- Backend tests confirm the backend already handled this correctly
- Frontend regex pattern now matches the backend behavior
Fixes#1645
