1A — /mesh/topology?include_coords=true enriches each node with
lat/lon fetched via Redis MGET on entity:{node_id} keys.
1B — APRS weather comment parser (poller/enrichment/aprs_weather.py)
extracts temp, humidity, pressure, wind, rain from Ultimeter/Davis
comment strings; wired into aprs.py for station_type=weather entities,
stored under identity.wx.
1C — SNR threshold alert infrastructure: mesh_link_alerts.py tracks
per-link SNR history and fires mesh_link_degraded events on the falling
edge with a cooldown gate; wired into _upsert_mesh_links in meshcore.py.
DB migration 10_mesh_alert_config.sql adds the per-source config table.
Feature 3 — APRS weather panel: AprsOverview shows a live conditions
card (temp/humidity/pressure/wind/rain) when identity.wx is present;
EntityDetail exposes a Weather tab for APRS weather stations alongside
the existing aircraft METAR tab.
pyMC poller — meshcore_pymc.py uses the `meshcore` Python library
(meshcore>=2.3.0) to connect directly to a MeshCore device over TCP
or serial, fetching the full contact table with adv_lat/adv_lon
coordinates and calling fetch_all_neighbours() per contact to capture
SNR as measured by remote nodes — a dimension unavailable via the
RemoteTerm REST/WS path.
Also notes: Feature 1 (APRS symbol color-coding) was already complete
in buildEntityLayers.ts (aprsColor, emergencyRingLayer, aprsLabelLayer).

Summary
This PR adds three major features to enhance mesh network monitoring and APRS weather station support:
MeshCore pyMC poller — A new direct-access poller for MeshCore devices that captures bi-directional link metrics (SNR measured by each remote node) via the
meshcorePython library, supporting both TCP and serial connections.Mesh link SNR threshold alerts — A new alert infrastructure that monitors per-link SNR history and fires
mesh_link_degradedevents when links drop below configured thresholds, with cooldown gating to prevent alert floods.APRS weather station support — Enhanced APRS poller to parse Ultimeter/Davis-style weather comments and display live conditions (temperature, humidity, wind, pressure, rainfall) in the entity detail panel.
