Use rms.auth.smtp_relay settings as the primary source for OTP mail transport (host/port/auth/tls/from/replyTo), with existing OTP/env values only as fallback. This lets OTP delivery work immediately when relay settings are already configured.
Make rms.auth.otp_email use SMTP transport with the same host/port/auth/tls settings model as smtp relay, with outbox fallback when SMTP is unavailable. Extend OTP plugin settings schema to expose standard SMTP parameters in plugin config.
Add the reusable RMS core application (server, web UI, plugins, tests, tools) with generic defaults, GPL licensing, and maintainer context documentation so deployments can consume this repo as software source independent of station-specific overlays.
