Add Meshtastic Infrastructure page

Lists the router sites the MeshMY team builds and maintains, with
general area, elevation, grid locator, hardware/antenna per band,
maintenance status, and links to Google Maps and the community mesh
map. Exact installation specifics (addresses, mounts, contacts) are
kept out; coordinates are rounded to ~11 m precision.
