- Set map height to 100% instead of fixed 280px
- Removed card-body padding to eliminate gap
- Added h-full class to ensure cards fill available height
- Added min-height of 320px for better UX
- Removed redundant styling from map container
The map now properly fills the entire card height and matches
the position information card height on larger screens.

- Fixed info page not receiving live updates by implementing callsign-specific PubSub topics
- Added automatic time counter for "Last Position" and other timestamps using JavaScript hook
- Optimized map updates to only move marker instead of reloading entire map
- Fixed APRS parser to properly handle [000/000/A=altitude format in comments
- Removed packet caching on info page for real-time updates
The info page now properly subscribes to updates for the specific callsign being viewed,
timestamps automatically count up without page refresh, and the map smoothly animates
marker position changes instead of flickering with full reloads.

When a new deployment occurs in k8s, all connected LiveViews now receive
a notification to update their deployment timestamp display.
Changes:
- Added DeploymentNotifier GenServer that broadcasts deployment events
- LiveViews subscribe to "deployment_events" PubSub topic
- When DEPLOYED_AT env var is set (k8s deployments), a notification is
sent after app startup
- LiveViews handle the deployment event and update their timestamp
This ensures that when a new version is deployed, users see the
deployment timestamp update in real-time without needing to refresh
their browser.

The map wasn't receiving real-time packet updates because:
1. LiveView wasn't subscribed to StreamingPacketsPubSub
2. LiveView wasn't handling {:streaming_packet, packet} messages
3. Packets weren't being broadcast to both PubSub systems
Changes:
- Added StreamingPacketsPubSub subscription with viewport bounds filtering
- Added handler for {:streaming_packet, packet} messages
- Update subscription bounds when map viewport changes
- Properly unsubscribe on LiveView termination
- Also broadcast packets to SpatialPubSub (in addition to StreamingPacketsPubSub)
Now the map only receives packets within its current viewport bounds,
reducing unnecessary data transfer and improving performance.

The 'Last Update' timestamp now correctly shows when the last real-time
packet was received, not when the map bounds changed or historical data
was loaded.
Changes:
- Removed timestamp update when map bounds change (was incorrectly
resetting the timer)
- Added periodic UI update timer (every 30 seconds) to refresh the
'time ago' display so it counts up properly (e.g., "2 minutes ago",
"5 minutes ago", etc.)
- The timestamp only updates when actual real-time packets are received
via PacketProcessor
Now the sidebar will show how long it's been since the last packet was
received, updating every 30 seconds to keep the display current.

Fixed multiple issues causing CI failures:
1. Removed unused @migration_timeout module attribute in migration
2. Fixed EncodingUtils doctests to include all fields returned by encoding_info
3. Fixed ETS table access errors in StreamingPacketsPubSub by moving cleanup
operations back to the GenServer process (ETS tables can only be modified
by their owner)
4. Fixed DBConnection.OwnershipError in DeviceCache by skipping database
access in test environment
The ETS fix works by collecting dead PIDs in the async task and sending
them back to the GenServer for cleanup, avoiding cross-process ETS access.

The :phg field was being added as a map to packet attributes, but it's
not a database field. PHG data should be split into individual fields
(phg_power, phg_height, phg_gain, phg_directivity) which are actual
database columns.
Removed the :phg map from being added to attributes. The put_phg_fields
function already handles extracting individual PHG components.
Updated tests to check for individual PHG fields instead of the map.

The APRS parser wasn't extracting altitude and PHG data from the comment
field. Added extraction functions to parse:
- Altitude from /A=XXXXXX format (converts to feet)
- PHG (Power-Height-Gain-Directivity) from PHGXXXX format
Also updated the comment cleaning to remove these technical details,
leaving only the human-readable station description.
Updated tests to properly use Packet.extract_additional_data() which
is where the parsing happens during packet processing.

Previously, the deployment timestamp was set to DateTime.utc_now() when
the application started, which meant it would always show as recent in
k8s environments where pods are recreated on each deployment.
This commit:
- Updates Release.init() to check for DEPLOYED_AT environment variable
- Falls back to current time if env var is not set (backwards compatible)
- Adds proper ISO8601 timestamp parsing with error handling
- Updates GitHub Actions deploy workflow to set DEPLOYED_AT during deployment
- Creates k8s patch file for future manual deployments
The deployment timestamp will now persist across pod restarts in k8s,
showing the actual deployment time rather than pod startup time.

Convert unsupported summary metrics to supported types:
- Use distribution() for latency/duration measurements with appropriate buckets
- Use last_value() for current state metrics (VM memory, queue lengths)
- Use counter() for cumulative metrics (packet counts, errors)
This eliminates the TelemetryMetricsPrometheus warnings about unsupported
summary metric types while maintaining proper metric semantics.

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.
