Lint & Test / test (push) Has been cancelled
- Replace URL-based image_source/url fields with image_asset_id/video_asset_id on StaticImagePictureSource and VideoCaptureSource (clean break, no migration) - Resolve asset IDs to file paths at runtime via AssetStore.get_file_path() - Add EntitySelect asset pickers for image/video in stream editor modal - Add notification sound configuration (global sound + per-app overrides) - Unify per-app color and sound overrides into single "Per-App Overrides" section - Persist notification history between server restarts - Add asset management system (upload, edit, delete, soft-delete) - Replace emoji buttons with SVG icons throughout UI - Various backend improvements: SQLite stores, auth, backup, MQTT, webhooks

An Asset represents an uploaded file (sound, image, video, or other)

stored on the server. Assets are referenced by ID from other entities
