v2.5.2 — PWA, new branding, bug fixes

Progressive Web App:
- Service worker with Workbox caching (map tiles, API, uploads, CDN)
- Web app manifest with standalone display mode
- Custom app icon with PNG generation from SVG
- Apple meta tags, dynamic theme-color for dark/light mode
- iOS safe area handling

New Branding:
- Custom NOMAD logo (icon + text variants for light/dark mode)
- Logo used in navbar, login page, demo banner, admin, PDF export
- MuseoModerno font for login tagline
- Plane takeoff animation on login
- Liquid glass hover effect on dashboard spotlight & widgets
- Brand images protected from save/copy/drag
- "made with NOMAD" footer on PDF exports

Bug Fixes:
- Fix mobile note reorder (missing tripId prop)
- Fix Atlas city counting (strip postal codes, normalize case)
- Fix Atlas country detection (add Japanese/Korean/Thai names)
- Fix PDF note positioning (use order_index instead of sort_order)
- Fix PDF note icons (render actual icon instead of hardcoded notepad)
- Fix file source badge overflow on mobile (text truncation)
- Fix navbar dropdown z-index overlap with mobile plan/places buttons
- Fix dashboard trip card hover contrast in dark mode
- Fix day header hover color matching place background in dark mode
- Shorten settings button labels on mobile

UI Improvements:
- Mobile navbar shows icon only, desktop shows full logo
- NOMAD version badge in profile dropdown
- Top padding before first item in day planner
- Improved drag & drop stability (larger drop zones, less flickering)
