- Add info-level logging to all mobile websocket handle_in callbacks to track
incoming messages (subscribe_bounds, update_bounds, search_callsign, etc.)
- Create LogFilter plug to exclude K8s healthcheck requests from Phoenix logs
- Filter logs for /health, /ready, and / endpoints to reduce noise from
continuous healthcheck probes
- Configure Plug.Telemetry to use custom log level function
This eliminates noisy healthcheck logs while providing better visibility
into mobile websocket API usage.
- Add safe check for ShutdownHandler process existence
- Handle case where ShutdownHandler might not be started yet
- Prevent GenServer.call errors in health checks
- Use Process.whereis and Process.alive? to verify process state
This fixes Sentry errors about 'no process' when health checks
try to call ShutdownHandler.shutting_down?()

This commit introduces a dual-mode caching and rate limiting system that can use
either Redis (for distributed deployments) or ETS/Cachex (for single-node setups).
Key changes:
- Add Cache abstraction layer that automatically switches between Redis and Cachex
- Implement RedisCache module with full distributed cache functionality
- Implement RedisRateLimiter with sliding window algorithm for accurate rate limiting
- Add RateLimiterWrapper to provide unified API for both implementations
- Update application startup to conditionally use Redis when REDIS_URL is set
- Migrate all cache operations to use the new Cache abstraction
- Support graceful fallback to ETS-based solutions when Redis is unavailable
The system automatically detects Redis availability via REDIS_URL environment
variable and switches between implementations without code changes. This enables
proper distributed caching and rate limiting in Kubernetes deployments while
maintaining backward compatibility for development environments.

Fixed ArgumentError in rate limiter by replacing cond statement with
proper case pattern matching. The cond was incorrectly evaluating
assignment expressions as truthy values instead of checking if headers
were empty lists.

- Updated IP geolocation to check CF-Connecting-IP header first
- Added support for X-Real-IP header as additional fallback
- Updated rate limiter to use same header priority for consistency
- Headers checked in order: CF-Connecting-IP > X-Forwarded-For > X-Real-IP > remote_ip
This ensures proper client IP detection when the site is behind Cloudflare.
