Subject: [PATCH] fix: ensure /tmp is writable by container user in Docker
 image

The scratch-based Docker image copies /tmp from the builder stage with
root ownership, but the container runs as UID 1000. SQLite needs a
writable temp directory for complex transactions (task position changes,
saved filter creation, data export), causing "disk I/O error: permission
denied" errors.

Closes go-vikunja/vikunja#2316
