Alex Vanderpot 02623e5559 neighbors: seattle->letsmesh region + fix path-edge prefix extraction
- Point the seattle region at the letsmesh broker (wss://mqtt-us-v1.letsmesh.net:443,
  topic meshcore/SEA) where Seattle traffic now lives.
- Fix a pre-existing bug in the path-edge extraction: `path` is a hex string of
  1-byte hop prefixes, so use substring(path, 2*i-1, 2) instead of
  hex(substring(path, i, 1)) (which re-hexed a single hex char and never matched
  the 2-char repeater prefixes -> path edges were always empty). Seattle now yields
  path edges again.

Verified on a full prod snapshot: the MV-backed "show all neighbors" query drops
from ~1.6s / 145M rows / 11.8 GiB to ~1ms / 108 rows / 3.8 KiB.

Alex Vanderpot cab5d821cf neighbors: serve from hourly refreshable materialized views
The two slow neighbor queries are converted to read precomputed tables that an
hourly REFRESH EVERY 1 HOUR materialized view maintains, instead of re-aggregating
meshcore_packets per request:

- meshcore_all_neighbor_edges: the global per-region edge graph (direct path_len=0
  adverts + repeater-prefix path edges) with endpoint details. getAllNodeNeighbors
  now filters it by region + bbox + lastSeen + has_location.
- meshcore_node_direct_neighbors: per-node direct adjacency (both directions) with
  neighbor details. getMeshcoreNodeNeighbors now filters it by node_public_key.

Also add the meshcore/SEA topic to the seattle region. Validated on a clean local
stack: migration 001->003 applies, both refreshable MVs create + refresh + populate.
