Phase 5: X-Accel-Redirect for /media/, UA Redis deny list, per-path counters

nginx:
- /media/ proxied through Gunicorn (sapl_general rate limit) instead of
  direct alias — Django middleware now runs on every media request
- /_accel/media/ internal location serves file bytes via X-Accel-Redirect

sapl/base/media.py (new):
- serve_media() gate: path traversal guard, auth redirect for
  documentos_privados/, per-path Redis counter, content-type metadata
  cache, X-Accel-Redirect response; falls back to Django serve() in DEBUG

sapl/middleware/ratelimit.py:
- RL_PATH_REQUESTS, RL_UA_BLOCKLIST, FILE_META_KEY constants
- _incr_with_ttl() extracted to module level (reused by media.py)
- Runtime UA deny list: _refresh_ua_blocklist() fetches rl:bot:ua:blocked
  SET from Redis (SMEMBERS, cached per worker, TTL=RATE_LIMITER_UA_BLOCKLIST_REFRESH);
  _is_redis_blocked_ua() tokenises UA and checks sha256 of each token

sapl/settings.py:
- RATE_LIMITER_UA_BLOCKLIST_REFRESH, MEDIA_PATH_COUNTER_TTL,
  MEDIA_FILE_CACHE_TTL added (all env-tunable via config())

plan/RATE_LIMITER_PLAN.md:
- Key schema table updated; media file serving section added;
  decision flow documented; UA deny list seed section expanded
