Extract duplicated SimpleEventEmitter class from multiple service files into a shared utility file `js/utils/eventEmitter.js`.
- Created `js/utils/eventEmitter.js` with unified implementation.
- Refactored `AuthService`, `NostrService`, `ModerationService`, and `PlaybackService` to use the shared class.
- Added support for constructor-defined context strings for improved error logging.
- Added comprehensive unit tests for `SimpleEventEmitter`.
- Verified changes with targeted service tests.

Introduces a race condition between the primary playback source (URL or Torrent) and a configurable timeout. If the primary source fails to reach the 'playing' state within the timeout window, the system automatically falls back to the alternative source.
- Adds `DEFAULT_PLAYBACK_START_TIMEOUT` to instance config (3000ms).
- Updates `PlaybackService` to implement timeout logic using `withTimeout` wrapper.
- Ensures proper cleanup of stalled attempts (resetting video element, destroying torrent client).
- Added `DEFAULT_PLAYBACK_SOURCE` to `config/instance-config.js` to allow choosing between "url" (default) and "torrent" priority.
- Updated `js/constants.js` to derive `URL_FIRST_ENABLED` flag from the configuration.
- Refactored `PlaybackService.execute()` in `js/services/playbackService.js` to robustly support "Torrent First" logic with fallback to URL, while maintaining "URL First" with fallback to Torrent.
- Added unit tests in `tests/services/playbackService_order.test.mjs` to verify playback order and fallback mechanics.
- Added source toggle UI in `components/video-modal.html`.
- Updated `VideoModal.js` to manage toggle visibility (only when both URL and Magnet exist), update peer/server counts, and dispatch `playback:switch-source` events.
- Updated `PlaybackService.js` to support a `forcedSource` option, allowing bypassing of the URL probe when "torrent" is forced.
- Updated `app.js` to listen for the toggle event and re-initialize playback with the forced source preference.
- Updated `tests/ui/helpers/jsdom-test-helpers.mjs` to expose necessary globals for JSDOM testing.
- Verified functionality with targeted updates and existing unit tests.
