feat(firmware): announce as an LXMF delivery destination (messageable)

Browse Source 
- switch the Reticulum announce from a plain "archy.messh" destination to
  "lxmf.delivery" so the bridge shows up as a messageable contact in
  Reticulum/LXMF clients; app_data is the display name "Archy-Messh"
- name_hash/dest_hash construction verified byte-identical to
  RNS.Destination.hash(id, "lxmf", "delivery")
- bump R-window LoRa preamble 16 -> 18 to match RNode firmware

Note: an RNode peer (.116) is not yet demodulating the bridge's R-PHY TX
(rxb stays flat) though the bridge decodes the RNode's announces fine and the
bridge's TX works on the MeshCore PHY — an asymmetric RadioLib-TX/RNode-RX
issue still to chase. Receiving LXMF message *content* is a further build.
