Implements automatic connection draining to balance load across cluster nodes:
- ConnectionMonitor tracks CPU usage and connection counts across nodes
- Triggers draining when node is overloaded (>70% CPU or 2x avg connections)
- LiveViews gracefully disconnect and reconnect to less loaded nodes
- Helps prevent single pod from handling all WebSocket connections
Also fixes Mic-E packet parsing to properly extract altitude data and
remove telemetry suffixes from comments.

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.

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.

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.

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.
