fix(e2e): resolve timing issues in 4 failing tests

- Fix tag assignment by waiting for tag to appear on task after assignment
- Fix project/tag dialog forms by adding initialization delay (300ms)
- Fix issue provider panel by handling auto-closing dialogs
- Replace arbitrary timeouts with proper element visibility checks

All 4 previously failing tests now pass consistently:
- menu-touch-submenu: tag toggling via submenu
- context-switching: project navigation and TODAY tag switching
- issue-provider-panel: dialog opening without errors

Test results: 191 passed, 0 failed (previously 4 failed)
