Successfully consolidated quick edit callback patterns in tui/app.py. **What was done:** 1. Added generic _handle_quick_edit() helper method at line 1345 in tui/app.py - Takes entity_type, entity_id, table_id, field_name, new_value, cursor_row, cursor_col, refresh_callback - Supports field_type parameter: 'single', 'nullable', 'list' - Handles table lookup, QuickEditHandler instantiation, and dispatching to appropriate handler method 2. Refactored all 8 quick edit callbacks to use the new helper: - _on_quick_edit_status (line 1390) - issue status - _on_quick_edit_priority (line 1399) - issue priority - _on_quick_edit_milestone (line 1408) - issue milestone with custom formatter - _on_quick_edit_labels (line 1425) - issue labels list - _on_quick_edit_project_status (line 1435) - project status - _on_quick_edit_project_owner (line 1444) - project owner (nullable) - _on_quick_edit_project_repos (line 1454) - project repos with CSV parsing - _on_quick_edit_project_tags (line 1467) - project tags list **Code reduction:** - Before: ~177 lines of boilerplate - After: 86 lines (including the 44-line helper method) - Net reduction: ~91 lines of duplicated code **Testing:** - All 832 tests passing - No syntax errors - Verified with: make test **Special handling:** - Milestone callback uses custom formatter to lookup milestone name - Repos callback parses CSV string into list before calling helper Commit: 4c99150 Branch: TRCKR-103 (merged to master)
