Remove in-app email opt-in; automate list sync outside the repo (#2759)

* Remove in-app email opt-in; automate list sync outside the repo

The 45-second-delayed subscribe modal was hard to time well and added
config surface (EMAILER_SECRET, email: in compass.yaml, a Kit service,
two API routes) that no self-hoster ever needs. New signups are now
added to Kit by a scheduled job in compass-calendar-infra instead, so
the app itself no longer knows the list exists. A tolerant `email:`
schema entry keeps existing self-hosted compass.yaml files valid on
upgrade. A one-line consent notice replaces the modal on the signup
form.

* Remove genericError and SUBSCRIBE_TO_UPDATES_TOAST_ID left orphaned

Both were only ever used by the Kit email code removed in the prior
commit; knip caught them as dead exports.
