* preserve runtime camera toggles across config saves
Runtime toggles (camera on/off, detect, recordings, snapshots, audio) mutate the in-memory config and persist an override to .runtime_state.json. /api/config/set re-parses yaml into a fresh FrigateConfig and swaps it in, re-applying the yaml and profile layers but dropping the runtime layer, so a camera turned off from the dashboard came back on when an unrelated camera was saved. The workers were never notified, so it only appeared to come back: the UI streamed go2rtc while ffmpeg stayed stopped.
Extract the startup replay into Dispatcher.apply_runtime_state() and call it from config_set after the swap, re-layering the overrides and republishing them so workers and the UI reconverge.
Remove the broad clear_runtime_state() from ProfileManager.update_config, which is only ever reached from config_set: with a profile active, every save wiped every camera's overrides from disk. The broad wipe stays in activate_profile, where a real profile switch does invalidate the steady state. Saves still clear the keys they rewrote via clear_runtime_state_for_yaml_keys, so yaml wins where the two disagree.
* sync runtime config on camera delete and prune its overrides
Deleting a camera re-parsed yaml into a fresh FrigateConfig but only rebound app.frigate_config and genai_manager, never dispatcher.config (nor profile_manager, stats_emitter, or the runtime overrides). The API and the dispatcher then drifted onto different config objects until the next config save re-synced them, so the API reported surviving cameras with their yaml enabled state while the dispatcher still acted on their real runtime state.
Extract the config swap that config_set already does into a shared swap_runtime_config helper and call it from both sites, so every collaborator is rebound and the surviving cameras' runtime toggles are re-layered. Also drop the deleted camera's persisted overrides via a new clear_camera so a camera later added under the same name does not inherit them.
* Pin ruff
* Add python upgrade fixes
This enables python upgrade checks in ruff to look for deprecated types and patterns. This namely fixes:
- usage of deprecated `Typing` which is now built in
- some specific exceptions which are caught and have new aliases
Some specific UP checks were also ignored as they are stylistic / unimportant and likely to cause bugs
* Remove async blocking calls
Use asyncio.to_thread on two remaining blocking calls to fix hanging event thread loop. Enable this specific rule to block it in the future.
* Use proper logging mechanism
* Correctly format logs
* Raise with context
When raising an exception include the from context to improve debugging
* Cleanup
