* feat(account): self-service login email change with double confirmation
New POST /api/account/email requests the change via the user session so
Supabase's AAL2 guard applies, and the account settings page gets an email
row with pending-confirmation state. Confirmation mails (both addresses)
and the /auth/callback email_change verification already existed; this
wires the missing initiation.

* feat(account): map email_exists to a 409 with Swedish copy
Changing to an address that already has an account is refused by GoTrue
(addresses are unique per auth user); surface that as a clear conflict
instead of the generic fallback.

* fix(account): trusted redirect origin + profiles.email sync trigger (skeptic findings)
- emailRedirectTo now derives from resolveRequestAppOrigin(): request.url
can be an internal origin behind a proxy (dead confirmation links on
self-hosted) and auth links must not follow attacker-chosen hosts;
registered white-label hosts keep their brand.
- New migration 20260828191950: sync_profile_email trigger mirrors
auth.users.email changes into profiles.email (member lists, notification
recipients, AGI/KU contact, invite dedup all read profiles.email), plus a
backfill for already-diverged rows. pg-real test included.
- Save button disabled while the same address awaits confirmation (no
rate-limit re-fires); GoTrue's 'error sending email change email' now maps
to the Swedish SMTP guidance.

* fix(account): idempotent repeat request for the pending address
CodeRabbit follow-up: a second POST for the address already awaiting
confirmation now returns the pending state without another GoTrue round
trip (no duplicate confirmation mails, no rate-limit burn). Claims-mapped
sessions lack new_email; GoTrue's send rate limit remains the backstop.
