feat: multiple improvements to library functionality (#50)

## Summary

This PR implements several improvements to the library application:

- Added start and finish date tracking for media items
- Added "Retired" category for abandoned media
- Implemented avatar-based user menu with dropdown navigation
- Added automatic background token refresh to prevent session expiry
- Created centralised logging system with frontend-to-API log forwarding
- Added toast notifications for error handling

## Changes

### Media Tracking (#41)
- Added `dateStarted` and `dateFinished` fields to Books, Games, Manga, Music, and Shows
- Updated TypeScript types, Prisma schema, and API services
- Added manual date input fields to frontend forms
- Properly converts HTML date strings to Date objects before API submission

### Retired Category (#43)
- Added `RETIRED` status to all media type enums
- Updated Prisma schema, frontend dropdowns, and filter buttons
- Added status label handling for retired items

### User Menu (#46)
- Replaced username text with avatar image in header
- Created dropdown menu with navigation items (Users, Audit, Suggestions)
- Added logout button to menu
- Implemented keyboard accessibility (tabindex, role, keyup handlers)

### Token Refresh (#44)
- Implemented automatic token refresh every 13 minutes in background
- Added proactive refresh to prevent token expiry during form filling
- Prevents users from losing form data due to expired sessions

### Centralised Logging (#1)
- Created `/log` endpoint on API to receive frontend logs
- Replaced API console.log calls with @nhcarrigan/logger
- Created ConsoleLoggerService to intercept all console methods on frontend
- Added global error handlers (window.error, unhandledrejection) on frontend
- Added process error handlers (uncaughtException, unhandledRejection, SIGTERM, SIGINT) on API
- All frontend console activity now forwarded to centralised logging

### Error Handling
- Created ToastService and ToastComponent for displaying errors
- Integrated with GlobalErrorHandler and HTTP interceptor
- Added accessibility features (keyboard navigation, ARIA attributes)
- Set toast opacity to 40% for optimal readability

### Testing & Build
- Fixed pre-existing test failure for GET / route (now returns version info)
- Added ESM module mocking (jsdom, marked, dompurify, @nhcarrigan/logger)
- Configured Jest with isolatedModules to handle TypeScript errors
- Excluded test-setup.ts from production build
- All tests passing (123 total)
- Build passing with no errors

## Test Plan

- [x] All tests pass (123 tests)
- [x] Build passes without errors
- [x] Lint passes (only pre-existing warnings)
- [x] Date fields work correctly on all media types
- [x] Retired status displays and filters properly
- [x] Avatar menu opens/closes correctly with keyboard and mouse
- [x] Token refresh prevents session expiry
- [x] Toast notifications appear for errors
- [x] Frontend logs forward to API successfully
- [x] Root route returns version information
