Summary
Adds a per-recipient mail rate limit so a bug or runaway webhook can't spam a user's mailbox.

mailLimiterfactory inapi/src/utils/limiter.ts(Mongo-backed, mirrors the existing auth limiter).sendMailnow splits thetofield, consumes one point per recipient, drops over-limit addresses, and logs each drop viainternalError('mail-rate-limited', …). If all recipientsare dropped the mail is skipped entirely.
mailsRateLimit { points, duration }(defaults: 500 / 24h), exposed via env vars and JSON schema. Test overrides set very low values to make limits exercisable.sendMailI18ncalls with non-http(s) link protocols.docs/architecture/emails.md.
