adlee-was-taken 6461a7f0c7 Add metered open signups, per-IP limits, and auth security hardening ...

Enables public beta signup metering: DAILY_OPEN_SIGNUPS env var controls
how many users can register without an invite code per day (0=disabled,
-1=unlimited, N=daily cap). Invite codes always bypass the limit.

Also adds per-IP signup throttling (DAILY_SIGNUPS_PER_IP, default 3/day)
and fail-closed rate limiting on auth endpoints when Redis is down.

Client dynamically fetches /api/auth/signup-info to show invite field
as optional with remaining slots when open signups are enabled.
