Fixed a critical bug where changes to project descriptions were not
being persisted when editing projects via Work > Projects > Edit Project.
The issue was caused by an incorrect CSS selector pattern in the form
submit handler that syncs the markdown editor content. The selector
`form[action*="projects/edit"]` failed to match URLs like
`/projects/123/edit` because the project ID breaks the substring match.
Changes:
- Updated form selector to use more generic pattern: `form[action*="/edit"]`
- Added explicit null checking with `if (form)` guard
- Enhanced error logging with console.error for debugging
- Improved code formatting and structure
Testing:
- Added integration test: test_edit_project_description
- Added smoke test: test_project_edit_page_has_markdown_editor
- All 166 project-related tests pass successfully
- No regressions introduced
