belviskhoremk 35e929c5e1 fix: harden Edge Function notification path per final review
Fixes issues raised by the whole-branch review before merge:

- Critical: the previous migration hardcoded the live production
  functions URL and anon key as the committed default, so every local
  `supabase db reset` silently pointed dev/test triggers at the real
  project. Adding a new migration instead of editing the already-applied
  one (checksum/drift safety), with local dev values as the committed
  default; production values are applied out-of-band, never committed.

- Important: verify_jwt=true plus sending the anon key as a bearer
  token didn't actually stop anyone, since the anon key is public
  (ships in the frontend bundle) — confirmed empirically, a request
  with a valid anon key but no shared secret now gets a real 401.
  Added a random shared secret known only to the database and the
  Edge Functions' secret store.

- Important: notification emails interpolated raw contact fields into
  HTML with no escaping. Added escapeHtml() and tests proving injected
  markup renders as literal text, not live markup.

- Important: the URL/key/secret functions moved from public to a
  private schema with EXECUTE revoked from anon/authenticated, closing
  an unintended PostgREST RPC endpoint (verified 404 after the fix).

Also adds a test:functions npm script now that Deno is confirmed
available and the shared email builders' tests pass (12 total incl.
the new escaping cases).
