fix(api): filter "Updated At" by updated_at column, not created_at

[sanjibani]

Summary

filter_updated_at in apps/api/plane/utils/issue_filters.py was passing created_at__date as the date_term to date_filter — a copy-paste from filter_created_at. The "Updated At -> is -> today" filter was therefore checking the issue's creation date instead of its last-modified date. Work items created earlier but updated today silently disappeared from the results.

The typo was in both the GET and POST branches of filter_updated_at. Replaced created_at__date with updated_at__date and added a focused unit test in apps/api/plane/tests/unit/utils/test_issue_filters.py that pins the column name.

Test plan

• New unit test TestFilterUpdatedAt covers the GET, GET-with-CSV, POST, and prefixed-cycle_issue__ cases, asserting every emitted filter key references updated_at and none reference created_at.
• Existing tests in tests/unit/utils/ continue to apply.

Summary by CodeRabbit

• Bug Fixes

  • Updated issue date filtering so updated_at searches now match the correct date field.
  • Improved filtering behavior for GET and POST requests, including comma-separated values, list-style inputs, optional prefixes, and empty filters.

• Tests

  • Added coverage for updated date filtering to verify the correct field is used across supported input formats and edge cases.

Poem

A rabbit hopped by moonlit code,
And sniffed where updated dates მიდ?
No created_at in sight tonight,
Just updated_at, all clean and right.
🐰✨ The filter trail is fresh and bright.
