The memory monitoring was incorrectly using total VM memory instead of
per-process memory, causing false positives whenever any process in the
system allocated memory.
Changes:
- Changed memory monitoring to per-process instead of total VM memory
- Reduced thresholds to reasonable per-process values (50MB diff, 100MB total)
- Increased minor GC trigger from 100 to 1000 packets to prevent GC after
every normal batch
This prevents detecting memory changes from other processes and eliminates
the constant GC warnings while still maintaining proper memory management.

The get_other_ssids function wasn't fetching symbol information from
the database, causing icons to display incorrectly. Updated the query
to include symbol_table_id and symbol_code fields and added them to
the packet struct so render_symbol_html can properly display the icons.

Reduced batch processing parameters to prevent excessive GC:
- Reduced batch_size from 500 to 100 packets
- Adjusted batch_timeout from 2000ms to 1000ms for faster processing
- Reduced max_demand from 750 to 300 to match smaller batches
- Updated hardcoded fallback from 500 to 100 in packet_consumer.ex
- Changed minor GC trigger from 500 to 100 packets to match batch size
These smaller batch sizes were proven to work well in production and
should significantly reduce the frequency of garbage collection while
maintaining good performance.

Increased memory thresholds from 10MB/20MB to 500MB/1GB since the server
has 15GB available memory. This prevents constant GC warnings while
maintaining memory safety.
Configured VM garbage collection settings in vm.args.eex:
- Enabled concurrent ports/sockets limit (+Q 65536)
- Set heap sizes and GC parameters optimized for better performance
- Added scheduler and binary heap settings
These changes will reduce unnecessary GC overhead and improve overall
application performance.

The PacketPipelineSetup was attempting to subscribe to a single
PacketConsumer process that doesn't exist. The application uses
PacketConsumerPool which automatically handles subscriptions for
multiple consumer processes, making PacketPipelineSetup redundant
and causing startup failures.

- Create PacketConsumerPool to run 3 parallel consumers (configurable)
- Increase max_demand from 250 to 750 total (250 per consumer)
- Fix timer management to properly cancel/restart on batch processing
- Configure proper GenStage subscriptions with backpressure control
- Allow unnamed consumers for pool usage
This 3x increase in processing capacity prevents the "Packet buffer full"
warnings by ensuring consumers can keep up with incoming packet rate.

This commit introduces several major performance improvements and adds
robust error handling for malformed HTTP requests:
Performance Optimizations:
- Add database migration with BRIN indexes for time-series data and partial
indexes for recent queries, significantly improving query performance
- Create global StreamingPacketsPubSub system for real-time packet distribution
with geographic bounds filtering using ETS for fast lookups
- Refactor PacketConsumer to use Stream module for memory-efficient processing,
preventing memory accumulation during batch operations
- Implement dedicated BroadcastTaskSupervisor pool for async broadcast operations,
preventing GenServer blocking on I/O
- Increase database connection pool from 25 to 45 (production) and 15 to 30 (dev)
for better concurrency support
Error Handling:
- Add SentryFilter to prevent Bandit.HTTPError from missing Host headers from
cluttering Sentry (common with bots/scanners)
- Configure custom 400 Bad Request error handling
- Filter out common bot/scanner paths from error reporting
All changes include comprehensive test coverage following TDD practices.

- Replaced direct Sentry SDK script tag with the Sentry Loader
- The loader handles CORS/network failures gracefully without breaking the app
- Moved Sentry configuration to use the onLoad callback
- Maintains the same configuration (100% sampling, BrowserTracing, etc.)
The Sentry Loader is a small inline script that:
1. Captures errors immediately (even before SDK loads)
2. Loads the SDK asynchronously
3. Handles load failures gracefully
4. Replays captured errors once SDK is loaded
This approach avoids CORS errors breaking the page load while still
providing error tracking when the SDK is accessible.

The frontend Sentry script was causing CORS and Content Security Policy errors.
Since backend error tracking is already configured with Sentry, the frontend
SDK is not essential and has been removed to prevent these errors.

- 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

The recent performance optimizations were causing packet buffer overflows
because the dynamic batch sizing was actually slowing down 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
