The operator-facing half of engagement Phase 1. README's stack table and
security section, plus both .env.example files, all pointed at the
removed Connect Gmail flow.

The env comments now name the three supported postures rather than one
provider — a relay as the recommendation, smtp.gmail.com:587 with an app
password as the shortest migration, an unauthenticated local MTA as the
third — and point at docs/website/UPGRADE_NOTES.md for the deployment
this actually happens to.

The OpenAPI spec is regenerated: two routes gone, three annotations
rewritten, and the dashboard's new warnings[] documented.

47c8b37d45 feat(email): remove Gmail OAuth2, put SMTP behind a transport registry
Engagement Phase 1 (docs/website/ENGAGEMENT.md §1.2a, §3.1, §3.2). A
subtraction and a replacement in one commit, because leaving the OAuth2
flow half-wired across a release is worse than either end state.

Deleted, per the §1.2a inventory: GET /admin/email/connect/start and
/connect/callback, the connectStart/connectCallback controllers with the
email_oauth_tx signed cookie, the PKCE verifier and CSRF nonce plumbing,
the https://mail.google.com/ scope, the borrowed `google` auth-providers
client, the OAuth2 nodemailer transport with its smtp.gmail.com:465
literals, the refresh-token decrypt in the model, and the client's
Connect Gmail button, redirect banner and six Gmail error strings.
`provider` and `refresh_token_enc` stay as columns under the
additive-only discipline, unread.

Added: a mail transport registry (server/src/engagement/transports) with
`smtp` as the sole registration. `credentialFields` is the single
declaration the admin form renders, the sanitizer filters against, and
the "is it secret" answer comes from, so adding a transport is a
registration rather than four edits. email_config gains transport /
credential_enc (one encrypted JSON blob, since the field list is the
transport's to declare) / reply_to.

All six call sites keep their exact failure contracts: the contact
form's mailto fallback, the invite's copyable link, the reset's generic
200, and sendTeamNotification's never-throws. One deliberate behaviour
change: `enabled` now gates every sender rather than only isConfigured()
— the connect flow used to set it as a side effect, and with a credential
form the toggle has to mean what it says.

Send-test becomes the real verification. Under OAuth2 the sender came
back from Google and was guaranteed to belong to the credential;
operator-typed, it can be refused, so failures name the sender and the
SPF/DMARC reason (§1.2a consequence 2).

G22, the silent degradation: an upgraded deployment backfills to smtp
with no credentials and every sink politely does nothing. The admin
dashboard now warns when the deprecated Gmail token is present and no
replacement credential is, so the one deployment this happens to is told.
A fresh install has never had mail and is not nagged.

Guardrails: new `npm run check:hosts` (§3.2 rule 4) with its own
self-test, wired into pr-checks before the install; routes.manifest and
routes.guards regenerated (-2 routes).
