Allow active TLE group, admit proxied same-origin requests, keep longest cooldown

- CelesTrak allowlist includes `active`, which Space Missions'
  getActiveTle() requests; unknown groups still answer 400.
- The CelesTrak gate uses admitSameSiteKeyless so the documented reverse
  proxy keeps working while foreign/opaque Origins and cross-site
  Sec-Fetch-Site are still refused with 403.
- A provider failure never shortens an existing cooldown (CelesTrak and
  Launch Library keep the later deadline).
- Tests: real getActiveTle() through the middleware, proxied app request
  vs unrelated Origin, concurrent failures finishing in both orders.
- docs/CURRENT-STATE.md: eight groups, keyless gate, non-shortening cooldown.
