- Replace N+1 get_latest_packet_for_callsign calls in RF path loading
with single get_latest_packets_for_callsigns batch query (DISTINCT ON)
- Change batch packet processing to collect marker removal IDs and push
one remove_markers_batch event instead of individual remove_marker calls
- Add callsignIndex reverse map (callsign_group → Set<markerID>) for O(1)
lookup in new_packet/new_packets handlers instead of scanning all markers
- Server tracks callsign replacements in prepare_packet_state, sends
convert_to_historical list so JS skips full markerStates scan
- Historical packets get red dot HTML server-side in build_minimal_packet_data
instead of JS createMarkerIcon generating it
- Add callsign_group field to all packet data output; server pre-sorts
by group with chronological order so JS iterates directly
- Normalize heat map intensity in Clustering.cluster_packets (min/50, cap 1.0)
instead of JS doing it per-point
- Remove buildPopupContent JS fallback and unused escapeHtml import;
server already provides popup in all data paths
- Batch real-time packet push_events: collect marker data across the
packet batch and send a single "new_packets" WebSocket message instead
of one per packet. JS handler processes all live→historical conversions
before adding new markers to avoid intra-batch conflicts.
- Batch RF path station queries: replace N+1 get_latest_packet_for_callsign
calls with a single DISTINCT ON query selecting only callsign + lat/lng.
- Add read_concurrency: true to streaming_packets_subscribers and :aprsme
ETS tables (read-heavy, rarely written).
- Remove dead GC code in PacketConsumer (threshold > 1000 unreachable with
max batch_size of 100).
Historical map loading previously fetched all 73 columns (SELECT *) from
the packets table (~2068 bytes/row). Added get_recent_packets_for_map/1
with select_map_fields/1 that fetches only the 22 columns needed for map
rendering (~200 bytes/row), yielding a ~3x query speedup.
Also removes unused all_packets tracking from PacketProcessor and
simplifies visible_packets cleanup in Index.
Replace case/cond/if blocks with multi-clause function dispatch
and pattern matching in function heads across 9 modules:
- WeatherUnits: case to multi-clause unit_system/1, unit_labels via do_unit_labels/1
- PacketUtils: if to pattern match on %{"id" => id}, multi-clause threshold/callsign
- SetLocale: case to multi-clause extract_locale/1
- IPGeolocation: if/cond to pattern match on conn, binary prefix matching for private_ip?
- DeviceIdentification: cond to extracted pattern_matches?/2
- MobileChannel: cond to multi-clause do_callsign_match/2
- PacketProcessor: cond to dispatch_visibility/6 on {in_bounds, has_marker} tuple
- PacketManager: destructure packet_state in heads, multi-clause maybe_cleanup/3
- AprsSymbol: case/if to multi-clause get_table_id/1, normalize_symbol_code/1
- Remove static Redis PubSub configuration from runtime.exs
- Add dynamic pubsub_config/0 function in application.ex
- Configure PubSub adapter based on cluster_enabled and REDIS_URL at startup
- Ensures proper initialization order for distributed deployments

This adds a "Last Update" section below the navigation that shows:
- Relative time ("less than a minute ago")
- Exact UTC timestamp ("2025-07-25 19:04 UTC")
Updates automatically whenever LiveView receives packet updates or map bounds changes.

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
