Add capture template system with in-memory defaults and split device settings UI

- Generate default templates (MSS, DXcam, WGC) in memory from EngineRegistry at startup
- Only persist user-created templates to JSON, skip defaults on load/save
- Add capture_template_id to Device model and DeviceCreate schema
- Remember last used template in localStorage, use it for new devices with fallback
- Split Device Settings dialog into General Settings and Capture Settings
- Add capture settings button (🎬) to device card
- Separate default and custom templates with visual separator in Templates tab
- Add capture engine integration to ProcessorManager
- Add CLAUDE.md with git commit/push policy and server restart instructions
- Add en/ru localization for all new UI elements
