Matiss Janis Aboltins db03d77e81 Handle missing accounts in SimpleFin batch sync (#7152)
* [AI] Fix SimpleFin batch sync crash when accounts are missing from response

When SimpleFin doesn't return data for all requested accounts during
batch sync, the code crashed with a TypeError accessing properties on
undefined, resulting in a generic "internal error" message for users.

This fix:
- Adds a guard in simpleFinBatchSync for missing account data, returning
  an ACCOUNT_MISSING error instead of crashing
- Propagates error entries from the SimpleFin response's errors map for
  accounts that have no data entry
- Adds a user-friendly ACCOUNT_MISSING error message in the UI suggesting
  to unlink and relink the account
- Adds test cases covering both scenarios

* Add release notes for PR #7152

* [AI] Fix SimpleFIN batch sync error_code TypeError

Fix "Cannot read properties of undefined (reading 'error_code')" that
occurs during SimpleFIN batch sync by:

1. Adding null check for downloadSimpleFinTransactions result in
   simpleFinBatchSync (sync.ts) - the function can return undefined
   when user token is missing

2. Adding .catch() handler on individual processBankSyncDownload
   promises so a single account failure doesn't crash the entire
   batch via Promise.all rejection

3. Using optional chaining on syncResponse.res?.error_code in app.ts
   and handling the case where res is undefined with proper error
   reporting

* [AI] Fix SimpleFin batch sync to emit ACCOUNT_MISSING for empty payloads

In the batch sync path, if a per-account download payload is an empty
object or is missing the transactions array, processBankSyncDownload
would crash and the error would be caught as INTERNAL_ERROR. Now we
check for these cases explicitly and emit ACCOUNT_MISSING instead,
while still allowing entries with error_code to propagate their
specific error.
