test(e2e): add end-to-end tests for playlist import, providers, and settings persistence

- Implemented tests for importing M3U playlists via native dialog.
- Added smoke tests for loading Xtream and Stalker content through IPC.
- Created tests to verify persistence of remote control settings across app restarts.
- Updated smoke tests to check for main window properties and workspace content rendering.

refactor(electron-backend): enhance store service and database path handling

- Modified store service to use a dynamic configuration directory based on environment.
- Refactored database connection to utilize new path utility functions for better path management.

fix(e2e): improve test selectors and structure for better reliability

- Updated test selectors in web-e2e tests to use role-based queries for better accessibility.
- Refactored settings tests to reduce redundancy and improve clarity.

chore(e2e): update TypeScript configuration for better inclusion of test files

- Adjusted tsconfig.json to ensure proper inclusion of e2e test files.
