Replace bracket notation (packet_data[key]) with Map.get/2 to avoid
UndefinedFunctionError when processing ParseError structs that don't
implement the Access behavior.

- Restored original PacketConsumer implementation from before optimizations
- Reverted to fixed batch size of 50 packets (original value)
- Removed SystemMonitor and InsertOptimizer from application startup
- Restored original config with buffer size 1000 and batch timeout 1000ms
- Removed all dynamic batch sizing and optimization logic
The recent performance optimizations were causing packet buffer overflows
because the dynamic batch sizing was actually slowing down processing.
Reverting to the simpler, working implementation that processes packets
consistently without buffer overflows.

- 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

Key improvements:
- Fix spatial query order: Apply bounds filtering BEFORE limit/offset
- Add zoom-level based batch sizing (20-100 packets per batch)
- Dynamic batch count based on zoom level (2-5 batches)
- Faster loading delays for high zoom levels (25ms vs 50ms)
- Include zoom level in cache keys for better cache efficiency
Performance benefits:
- Zoomed in far (zoom 15+): 2 batches of 20 packets each
- Moderately zoomed (zoom 12-14): 3 batches of 35 packets each
- Medium zoom (zoom 8-11): 4 batches of 50 packets each
- Zoomed out (zoom <8): 5 batches of 75-100 packets each
This ensures packets are loaded from the current viewport first,
dramatically reducing load times when zoomed in.
