notifications.html: add Home Assistant section with two collapsible
blocks — Connection (HA URL + Long-Lived Access Token) and Inbound
webhook (webhook ID with endpoint URL hint showing the username).
Token field uses keep-existing pattern (blank = no change).
settings.py: wire ha_url, ha_token, ha_webhook_id through
_notifications_page() template substitution and save_notifications()
POST handler. Preserves existing HA config fields (persona, tier,
role, tools) on save.
TODO__Agents.md: add Home Assistant integration planning section
(event design, richer payload template, HA API tools).

Notifications page:
- NC Talk section expanded: url, bot_secret, notification_room,
nc_username, nc_app_password — all fields from channels.json now editable
- Per-channel sections use <details>/<summary> collapsibles; auto-open
when values are present
- Secrets use type=password with "leave blank to keep" semantics
- Google Chat outbound webhook in its own collapsible section
Account settings:
- HTTP POST Allowlist section added (same textarea pattern as email allowlist)
- POST /settings/http-allowlist route saves home/{user}/http_allowlist.json
- Example placeholder shows ha.dgrzone.com and n8n patterns

Adds GET /settings/notifications (dedicated page with channel form + two
test buttons) and updates POST /settings/notifications to render that page.
Settings page now shows a compact link card instead of the full form.
