- Increased packet buffer size from 1,000 to 10,000 to handle traffic spikes
- Removed InsertOptimizer dynamic batch sizing that was slowing processing
- Reverted to fixed batch size of 200 for consistent performance
- Simplified insert options to use static configuration
- Added telemetry metrics for buffer overflow and utilization monitoring
- Fixed unused variable warning in packet_consumer.ex
The root cause was the recent performance optimizations that introduced
dynamic batch sizing, which actually degraded performance and caused
the producer buffer to overflow when the consumer couldn't keep up.

- Fixed InsertOptimizer returning map instead of keyword list for Ecto
- Increased batch size ranges to handle high load (100-800 packets)
- Improved consumer responsiveness:
- Reduced batch timeout from 1000ms to 500ms
- Process batches at 80% capacity for better throughput
- Reduced adjustment interval from 10s to 5s
- Added comprehensive logging for debugging buffer status
- Created integration tests for packet pipeline
- Coordinated batch sizing between SystemMonitor and InsertOptimizer

- Renamed predicate functions to follow Elixir conventions:
- is_finite? → finite?
- is_finite_number? → finite_number?
- is_finite_float? → finite_float?
- Fixed all function returns to ensure proper nil handling
- Applied mix format to all files
- All tests pass with no compilation warnings

Security improvements:
- Added sanitize_numeric_string to remove dangerous characters
- Limited input string length to prevent DoS attacks (20 chars for numbers)
- Added is_finite? checks to prevent infinity/NaN values
- Validate coordinate ranges (lat: -90 to 90, lng: -180 to 180)
- Added safe_parse_coordinate with proper validation
- Updated to_float in EncodingUtils with security validations
- Protected against integer overflow in coordinate conversions
- Added sanitize_path_string for APRS path validation
All coordinate inputs from users are now:
1. Sanitized to remove injection characters
2. Length-limited to prevent resource exhaustion
3. Validated for finite values (no infinity/NaN)
4. Checked against valid geographic ranges
5. Given safe fallback defaults

- Implemented dual-strategy pruning based on overage size
- Small overages (<10 packets): Only remove exactly what's needed
- Large overages: Batch prune with 20% buffer to reduce frequency
- Used Map.drop for more efficient bulk deletion
- Added Stream for lazy evaluation in small overage case
- Reduces complexity from O(n log n) on every insertion to:
- O(k log k) for small overages where k << n
- Amortized O(n log n) for large overages with buffering
- This significantly improves performance when managing thousands of packets

- Fixed PHG parsing test to match actual parser behavior
- Fixed movement test to properly handle batch loading behavior
- Movement test now sets bounds and uses higher zoom level
- Added helper function to flush events during test setup
- All tests now passing with clean compilation
