Phase 1-4: Redis infra, rate limiter middleware, cache layer, nginx hardening

docker/Dockerfile:
- GeoIP offline build with MaxMind secret; optional build args for
  graphviz, poppler, psql client; envsubst for nginx burst vars

docker/docker-compose.yaml:
- saplredis service (redis:7-alpine, allkeys-lru, 512 MB)
- REDIS_URL + CACHE_BACKEND wired into sapl service

docker/startup_scripts/start.sh:
- configure_redis_cache(): builds CACHES dict, sets REDIS_CACHE waffle
  switch, falls back to file cache gracefully
- POD_NAMESPACE resolution (k8s Downward API → hostname fallback)
- DATABASE_URL exported before migrate

docker/k8s/redis/ (moved from docker/k8s/):
- redis-configmap.yaml, redis-deployment.yaml, redis-service.yaml
- ClusterIP service on port 6379, sapl-redis namespace

docker/k8s/sapl-k8s.yaml:
- REDIS_URL env var injected; app.kubernetes.io/name=sapl label for
  fleet-wide discovery

sapl/middleware/test_ratelimiter.py:
- Unit tests for RateLimitMiddleware with mocked Redis

scripts/test_ratelimiter.py:
- CLI smoke-test: fires N requests and reports first 429

Removed: rate-limiter-v2.md (content migrated to plan/RATE_LIMITER_PLAN.md),
         scripts/test_ratelimiter.sh (replaced by .py),
         docker/k8s/README.md (merged into plan/RATE_LIMITER_PLAN.md),
         docker/scripts/redis_populate_test_data.py (renamed to redis_inject_test_data.py)

Phase 1: shared Redis pod — Django dual-backend cache + startup wiring

django/settings.py:
- REDIS_URL / CACHE_BACKEND env vars read at startup (written by start.sh)
- CACHES['default'] (DB0, KEY_PREFIX='sapl') switches between django-redis
  and FileBasedCache transparently; IGNORE_EXCEPTIONS=True for graceful
  degradation on Redis failure
- CACHES['ratelimit'] (DB1, no prefix) for cross-pod rate-limit counters
- RATELIMIT_USE_CACHE = 'ratelimit'
- Connection pool capped at 6/worker (1,200 pods × 2 workers × 6 = 14,400
  peak connections; maxclients=20,000 gives 40% headroom)

start.sh:
- resolve_redis_url(): reads REDIS_URL from local namespace Secret (envFrom)
  or falls back to global cluster Secret via k8s API
- configure_redis_cache(): ensures REDIS_CACHE waffle switch row exists (off)
- resolve_cache_backend(): reads waffle switch; sets CACHE_BACKEND=redis|file
- wait_for_redis(): blocks until Redis reachable; falls back gracefully
- write_env_file() now persists REDIS_URL + CACHE_BACKEND into pod .env

k8s manifests (docker/k8s/):
- redis-configmap.yaml: no persistence, allkeys-lru, maxmemory=5gb,
  maxclients=20000, activedefrag, 4 databases
- redis-deployment.yaml: redis:7-alpine, 1 replica, liveness/readiness probes,
  1Gi request / 6Gi limit
- redis-service.yaml: ClusterIP on port 6379

requirements: add django-redis==5.4.0
