Camera profile support (#22482)

* add CameraProfileConfig model for named config overrides

* add profiles field to CameraConfig

* add active_profile field to FrigateConfig

Runtime-only field excluded from YAML serialization, tracks which
profile is currently active.

* add ProfileManager for profile activation and persistence

Handles snapshotting base configs, applying profile overrides via
deep_merge + apply_section_update, publishing ZMQ updates, and
persisting active profile to /config/.active_profile.

* add profile API endpoints (GET /profiles, GET/PUT /profile)

* add MQTT and dispatcher integration for profiles

- Subscribe to frigate/profile/set MQTT topic
- Publish profile/state and profiles/available on connect
- Add _on_profile_command handler to dispatcher
- Broadcast active profile state on WebSocket connect

* wire ProfileManager into app startup and FastAPI

- Create ProfileManager after dispatcher init
- Restore persisted profile on startup
- Pass dispatcher and profile_manager to FastAPI app

* add tests for invalid profile values and keys

Tests that Pydantic rejects: invalid field values (fps: "not_a_number"),
unknown section keys (ffmpeg in profile), invalid nested values, and
invalid profiles in full config parsing.

* formatting

* fix CameraLiveConfig JSON serialization error on profile activation

refactor _publish_updates to only publish ZMQ updates for
sections that actually changed, not all sections on affected cameras.

* consolidate

* add enabled field to camera profiles for enabling/disabling cameras

* add zones support to camera profiles

* add frontend profile types, color utility, and config save support

* add profile state management and save preview support

* add profileName prop to BaseSection for profile-aware config editing

* add profile section dropdown and wire into camera settings pages

* add per-profile camera enable/disable to Camera Management view

* add profiles summary page with card-based layout and fix backend zone comparison bug

* add active profile badge to settings toolbar

* i18n

* add red dot for any pending changes including profiles

* profile support for mask and zone editor

* fix hidden field validation errors caused by lodash wildcard and schema gaps

lodash unset does not support wildcard (*) segments, so hidden fields like
filters.*.mask were never stripped from form data, leaving null raw_coordinates
that fail RJSF anyOf validation. Add unsetWithWildcard helper and also strip
hidden fields from the JSON schema itself as defense-in-depth.

* add face_recognition and lpr to profile-eligible sections

* move profile dropdown from section panes to settings header

* add profiles enable toggle and improve empty state

* formatting

* tweaks

* tweak colors and switch

* fix profile save diff, masksAndZones delete, and config sync

* ui tweaks

* ensure profile manager gets updated config

* rename profile settings to ui settings

* refactor profilesview and add dots/border colors when overridden

* implement an update_config method for profile manager

* fix mask deletion

* more unique colors

* add top-level profiles config section with friendly names

* implement profile friendly names and improve profile UI

- Add ProfileDefinitionConfig type and profiles field to FrigateConfig
- Use ProfilesApiResponse type with friendly_name support throughout
- Replace Record<string, unknown> with proper JsonObject/JsonValue types
- Add profile creation form matching zone pattern (Zod + NameAndIdFields)
- Add pencil icon for renaming profile friendly names in ProfilesView
- Move Profiles menu item to first under Camera Configuration
- Add activity indicators on save/rename/delete buttons
- Display friendly names in CameraManagementView profile selector
- Fix duplicate colored dots in management profile dropdown
- Fix i18n namespace for overridden base config tooltips
- Move profile override deletion from dropdown trash icon to footer
  button with confirmation dialog, matching Reset to Global pattern
- Remove Add Profile from section header dropdown to prevent saving
  camera overrides before top-level profile definition exists
- Clean up newProfiles state after API profile deletion
- Refresh profiles SWR cache after saving profile definitions

* remove profile badge in settings and add profiles to main menu

* use icon only on mobile

* change color order

* docs

* show activity indicator on trash icon while deleting a profile

* tweak language

* immediately create profiles on backend instead of deferring to Save All

* hide restart-required fields when editing a profile section

fields that require a restart cannot take effect via profile switching,
so they are merged into hiddenFields when profileName is set

* show active profile indicator in desktop status bar

* fix profile config inheritance bug where Pydantic defaults override base values

The /config API was dumping profile overrides with model_dump() which included
all Pydantic defaults. When the frontend merged these over
the camera's base config, explicitly-set base values were
lost. Now profile overrides are re-dumped with exclude_unset=True so only
user-specified fields are returned.

Also fixes the Save All path generating spurious deletion markers for
restart-required fields that are hidden during profile
editing but not excluded from the raw data sanitization in
prepareSectionSavePayload.

* docs tweaks

* docs tweak

* formatting

* formatting

* fix typing

* fix test pollution

test_maintainer was injecting MagicMock() into sys.modules["frigate.config.camera.updater"] at module load time and never restoring it. When the profile tests later imported CameraConfigUpdateEnum and CameraConfigUpdateTopic from that module, they got mock objects instead of the real dataclass/enum, so equality comparisons always failed

* remove

* fix settings showing profile-merged values when editing base config

When a profile is active, the in-memory config contains effective
(profile-merged) values. The settings UI was displaying these merged
values even when the "Base Config" view was selected.

Backend: snapshot pre-profile base configs in ProfileManager and expose
them via a `base_config` key in the /api/config camera response when a
profile is active. The top-level sections continue to reflect the
effective running config.

Frontend: read from `base_config` when available in BaseSection,
useConfigOverride, useAllCameraOverrides, and prepareSectionSavePayload.
Include formData labels in Object/Audio switches widgets so that labels
added only by a profile override remain visible when editing that profile.

* use rasterized_mask as field

makes it easier to exclude from the schema with exclude=True
prevents leaking of the field when using model_dump for profiles

* fix zones

- Fix zone colors not matching across profiles by falling back to base zone color when profile zone data lacks a color field
- Use base_config for base-layer values in masks/zones view so profile-merged values don't pollute the base config editing view
- Handle zones separately in profile manager snapshot/restore since ZoneConfig requires special serialization (color as private attr, contour generation)
- Inherit base zone color and generate contours for profile zone overrides in profile manager

* formatting

* don't require restart for camera enabled change for profiles

* publish camera state when changing profiles

* formatting

* remove available profiles from mqtt

* improve typing
