fix(electron): suppress DevTools source map error for Capacitor SQLite plugin

Remove sourceMappingURL comment from plugin.js in @capacitor-community/sqlite to
prevent Electron DevTools from attempting to load the source map via the custom
capacitor-electron:// protocol. This eliminates harmless but noisy 404 warnings
in development. No impact on runtime or debugging.

- Remove //# sourceMappingURL=plugin.js.map from plugin.js
- Confirmed plugin.js.map exists for manual inspection if needed
- No changes to app logic or build process
