test: add coverage for Redis caching layer
Add 29 new tests covering previously uncovered code paths:
- redis.py: delete(), close(), string value decoding
- cache.py: serialization branches (pydantic, dict, list), set error fallback
- app.py: lifespan Redis init (enabled/disabled), cache close on shutdown
- app.py: X-Cache middleware (HIT/MISS/no-status)
- app.py: /health/ready Redis status (connected/unreachable/omitted)
- cli.py: Redis banner output, create_app param passthrough
- Route key builders: dashboard/stats, dashboard/message-activity,
channels, messages

feat: add optional Redis caching layer for API endpoints
Add Redis-backed response caching for read-heavy API endpoints (nodes,
advertisements, messages, channels, dashboard, profiles) with configurable
TTL, key prefix isolation, and graceful fallback when Redis is unavailable.
New files:
- common/redis.py: CacheBackend, NullCache, RedisCacheBackend
- api/cache.py: @cached decorator, sorted_query_string helper
- tests/test_api/test_cache.py: 23 unit tests
Changes:
- pyproject.toml: add redis[hiredis] dependency
- common/config.py: 8 Redis settings on APISettings
- api/cli.py: Redis Click options + startup banner
- api/app.py: Redis lifespan init/cleanup, X-Cache middleware, health check
- 6 route files: apply @cached decorator to list endpoints
- docker-compose.yml: Redis service (cache profile), env vars
- docker-compose.dev.yml: Redis port exposure
- .env.example, README.md, AGENTS.md, docs/upgrading.md: documentation
Redis is disabled by default (REDIS_ENABLED=false). Enable with
--profile cache and REDIS_ENABLED=true.
