Plan Remaining Siesta to Playwright Test Migrations

This task is to identify all remaining Siesta unit tests that need to be migrated to the Playwright test runner and to create a corresponding ticket for each one. This will provide a complete and actionable backlog for the test migration effort.

Acceptance Criteria

1. Generate a complete list of all test files within the test/siesta/tests/ directory.
2. Compare this list against the already completed migrations to identify the remaining files.
3. For each remaining Siesta test file, create a new, individual ticket in the .github/ISSUE/ directory.
4. Each new ticket must follow the established format (e.g., "Ticket: Convert [filename] Test from Siesta to Playwright").
5. Update the main epic ticket (epic-enhance-workflow-with-mandatory-unit-testing.md) to list all newly created "To Do" tickets under the "Test Migrations" section.
