- Add reporter_options with buckets to each distribution metric
- Remove incorrect top-level buckets configuration
- Define buckets array once and reuse for all distribution metrics
The TelemetryMetricsPrometheus library requires buckets to be specified
in reporter_options for each individual distribution metric, not at the
reporter configuration level.

- Move buckets configuration from individual metrics to reporter level
- Configure default buckets for all distribution metrics in reporter options
- Remove buckets from individual metric definitions to prevent ArgumentError
- This fixes the pod crash due to "missing required buckets property" error
The TelemetryMetricsPrometheus library requires buckets to be configured
at the reporter level rather than per-metric for distribution types.

Convert unsupported summary metrics to supported types:
- Use distribution() for latency/duration measurements with appropriate buckets
- Use last_value() for current state metrics (VM memory, queue lengths)
- Use counter() for cumulative metrics (packet counts, errors)
This eliminates the TelemetryMetricsPrometheus warnings about unsupported
summary metric types while maintaining proper metric semantics.

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.

Both /status and /status.json endpoints now show cluster-wide APRS-IS
connection status instead of just local node status.
Features:
- get_cluster_aprs_status() checks all nodes in cluster via RPC
- Returns status from any connected node (usually the leader)
- Shows cluster info: total nodes, connected nodes, leader node
- Graceful fallback to local status in non-clustered mode
- Enhanced status page UI with cluster information display
This ensures status pages accurately reflect the true APRS-IS
connection state across the entire cluster.

The cleanup_stale_registrations function was calling Process.alive?
on remote PIDs, which causes an ArgumentError. Fixed by:
- Using Process.alive? only for local PIDs
- Using :rpc.call for remote PID liveness checks
- Adding proper error handling for RPC failures
- Cleaning up registrations for disconnected nodes
This prevents GenServer crashes when checking leader status.

- Leader election now waits for other nodes to connect before starting
- Added cleanup of stale global registrations from disconnected nodes
- Only starts election after cluster is established in clustered mode
- Non-clustered mode continues to elect immediately
This prevents both nodes from becoming leaders when they start
before the cluster is fully formed.
