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.

Fixed the esbuild errors during Docker build where npm packages couldn't
be resolved. The issue was caused by node_modules being excluded from
the Docker build context in .dockerignore.
Implemented a proper vendor bundle strategy following Phoenix 1.7+ patterns:
- Created vendor.js that bundles all npm dependencies (Leaflet, Chart.js,
topbar) and their CSS files into a single pre-built bundle
- Added vendor esbuild profile in config.exs with proper CSS/image loaders
- Updated mix.exs to build vendor bundle before app bundle in assets.deploy
- Modified JavaScript imports to use globally loaded libraries from vendor
bundle instead of importing from node_modules
- Added vendor.js script tag to root.html.heex before app.js
This approach avoids Docker build failures by pre-bundling all vendor
dependencies, eliminating the need for node_modules during production builds.

Fixed issue where stationary stations like K5SGD-D were showing multiple
positions due to minor GPS accuracy variations. The previous 15-meter
threshold was too strict for typical GPS drift which can vary 5-30 meters.
- Increased default threshold in GeoUtils from 10m to 50m
- Updated packet processor to use 50m threshold for movement detection
- Verified with K5SGD-D showing ~24m variations that are now ignored

This change eliminates all external CDN dependencies by bundling JavaScript
libraries locally using esbuild. All vendor files are now served from the
application's own assets, improving reliability and privacy.
Changes:
- Created assets/js/vendor.js to bundle all external libraries
- Added vendor bundle configuration to esbuild in config files
- Updated all templates to use local vendor.js instead of CDN scripts
- Created download-vendor-files.sh script to fetch vendor libraries
- Added vendor files to .gitignore (they're downloaded during setup)
- Updated CSS imports to include vendor stylesheets
- Added vendor build step to assets.deploy mix task
Bundled libraries:
- Leaflet 1.9.4 (mapping library)
- Leaflet.heat 0.2.0 (heatmap plugin)
- Leaflet.markercluster 1.5.3 (marker clustering)
- OverlappingMarkerSpiderfier 0.2.6 (overlapping marker handling)
- Chart.js 4.5.0 (charting library)
- chartjs-adapter-date-fns 3.0.0 (date adapter for Chart.js)
All functionality tested and working correctly with local bundles.

Implemented URL persistence for map settings to preserve user preferences:
- Added `trail` parameter for trail duration (1, 6, 12, 24, 48, 168 hours)
- Added `hist` parameter for historical data hours (1, 3, 6, 12, 24 hours)
- Parameters only appear in URL when different from default value (1 hour)
Changes:
- Updated handle_url_update to include trail and hist parameters
- Modified mount to parse these parameters on page load
- Updated handle_params to parse parameters on URL changes
- Added update_url_with_current_state helper function
- Modified update_trail_duration and update_historical_hours event handlers
to update URL when settings change
- Fixed finalize_mount_assigns to preserve parsed values
This allows users to share or bookmark URLs with specific trail duration

When changing trail duration and historical data settings, historical positions
would show up on the map but trail lines wouldn't connect them. This was caused
by a mismatch between trail ID generation and callsign extraction.
## Changes
- Fix getTrailId() to properly extract base callsigns from historical marker IDs
- Add setTrailDuration() method to TrailManager for dynamic duration updates
- Add LiveView event to synchronize trail duration changes with client
- Add comprehensive tests for historical ID handling
## Problem
Historical markers have IDs like "hist_CALLSIGN_123" but getTrailId() was
returning the full ID while TrailManager.extractBaseCallsign() extracted just
"CALLSIGN", creating separate trails instead of connected ones.
## Solution
Updated getTrailId() to extract base callsigns from historical IDs using the
same logic as TrailManager, ensuring all positions from the same station use
the same trail ID and connect properly.

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.
