feat(v1.8.0): IMPL_03 Sync Settings - Trigger Visual Separation

- Restructure settings into two clear sections: Triggers & Performance
- Add sync_section_triggers and sync_section_network_performance strings (DE + EN)
- Group all 5 triggers together (Instant: onSave/onResume, Background: WiFi/Periodic/Boot)
- Move WiFi-Only + Parallel Downloads to separate "Network & Performance" section
- Place Manual Sync info card after triggers, before Performance section

Improves UX by logically grouping related settings. Triggers are now
in one cohesive block, separated from network/performance options.
Easier to find and understand sync configuration.
