Pull Request Description:

## Description
This PR introduces a major modernization of the ScoutingPASS application tailored for the 2026 FRC season. The updates focus on improving usability in loud, offline environments, modernizing the UI/UX, and introducing "smart scouting" capabilities to reduce the cognitive load on scouts.

### Key Features & Changes
* **PWA & Offline Reliability**: Implemented a Service Worker (`sw.js`) and `manifest.json`. The application is now installable as a standalone Progressive Web App (PWA) and works 100% offline with reliable caching.
* **Modern Responsive UI**: 
  * Replaced the rigid sequential swiping flow with a sticky bottom Navigation Bar for instant access to any phase (Auton, Teleop, etc.).
  * Extracted hardcoded inline styles into centralized CSS variables and implemented a sleek, built-in Dark Mode.
* **Smart Scouting Tools**:
  * **Offline Match Queue**: Completed matches are now securely saved to the browser's `localStorage` upon clearing the form.
  * **History Panel**: A new dedicated tab to view saved matches and seamlessly re-generate QR codes if a scanner fails.
  * **Haptic Feedback & Validation**: Added physical tap feedback via `navigator.vibrate` and robust validation to prevent generating incomplete data (e.g. missing Match or Team numbers).
* **Multi-Language (i18n) Engine**: Built a dynamic `translations.js` engine. Added out-of-the-box English and Turkish support for both static UI elements and dynamic configuration strings (e.g., "Fuel Scored" -> "Kazanılan Yakıt").

## Verification
- [x] Verified PWA offline installation and caching via browser DevTools.
- [x] Tested responsive Navigation Bar and Dark Mode styling on simulated mobile and tablet devices.
- [x] Confirmed Match History correctly saves to local storage and successfully re-renders QR codes on demand.
- [x] Verified real-time language switching correctly maps English and Turkish dictionaries without breaking configuration data.

**Note**: All changes have been modularized using clean Conventional Commits to ensure ease of review.
