Extract nested logic into helper functions to improve readability:
- regex_cache.ex: Extract compile_and_cache/1 for regex compilation and caching
- connection_monitor.ex: Extract calculate_scheduler_utilization/1 for CPU stat calculation
- device_identification.ex: Extract fetch_devices_from_url/0 for HTTP request handling

- Optimized list concatenation in PacketConsumer from O(n) to O(1) by prepending events
- Refactored coordinate rounding to avoid recreating anonymous functions on each call
- Added database indexes for case-insensitive searches on upper(sender) and upper(base_callsign)
- Implemented RegexCache to avoid recompiling regex patterns for wildcard device matching
- Added compound index on upper(sender) with received_at for efficient sorted queries
These changes improve performance in hot paths:
- Packet batching is now more efficient with better list operations
- Coordinate processing avoids function allocation overhead
- Database queries using UPPER() now use functional indexes
- Device wildcard matching no longer recompiles regex on every lookup
