fix: Disable Spotify widget by default

The Spotify 'Now Playing' overlay widget was appearing even when
the Spotify Controller plugin was not enabled.

CHANGES:
- Set 'spotify' overlay widget to enabled: False in default settings
- Removed Spotify from dashboard default widgets
- Both settings.py and settings_secure.py updated

The widget can still be manually enabled by users who want it:
1. Edit config/settings.json
2. Set overlay_widgets.spotify.enabled to true
3. Or use the overlay widget controls

This fixes the issue where the Spotify widget appeared even when
the plugin wasn't enabled.
