Theme preference stored in localStorage (auto follows the OS setting).
The chosen data-theme attribute is applied synchronously in <head> to
avoid any flash of unstyled content. CSS custom properties handle all
surface, text, border and input colours across every page. The
Appearance section on the profile page lets each user switch modes.

Notification channels are now managed through a proper web form instead
of a raw YAML textarea. Any authenticated user can create channels; private
channels (owner-scoped) are hidden from other users. The user profile
channel selector becomes a tag/chip picker with a "My Channels" CRUD section.
- settings.py: add CHANNEL_TYPE_SCHEMAS for all 6 notifier types; channel
section switches to section_mode="channels"; cards include owner/private/min_level
- configio.py: add apply_channel() and delete_channel() for per-entry CRUD
- notify.py: strip owner/private metadata before dispatching to drivers
- http.py: add GET/POST /api/0/notification_channels, PUT/DELETE /{name},
GET /api/0/notification_channel_types; visibility helper filters private
channels per user; PUT /api/0/users/me validates against visible channels
- settings.html: card grid with edit/delete per channel; add/edit modal
with type dropdown and dynamically rendered type-specific fields
- profile.html: chip picker replaces checkbox list; My Channels section
for creating/editing/deleting user-owned channels
- tests: update test_settings_sections, test_http_users_me; add
test_notification_channels_api (16 new tests, 46 total passing)
