feat(mesh): Phase 1/2b/4/5 primitives — ReadReceipt/Forward/Edit/Delete/Presence/Contacts/ChannelInvite + chunked send + unified inbox RPCs

Adds every remaining wire variant and RPC needed to finish the Telegram-quality
mesh plan in a single pass:

* Variants 15 ReadReceipt, 16 Forward, 17 Edit, 18 Delete, 20 Presence,
  21 ChannelInvite; plus MeshMessageType::ContactCard(22) cleanup (was
  enum-only, now wired through from_u8/label/from_label).
* MessageType::from_label() as the inverse of label() — used by the Forward
  path to re-encode a stored typed body back through its original variant.
* RPCs: mesh.send-psbt (variant 3 was previously enum-only),
  mesh.send-read-receipt, mesh.forward-message, mesh.edit-message,
  mesh.delete-message, mesh.broadcast-presence, mesh.presence-list,
  mesh.contacts-list, mesh.contacts-save, mesh.contacts-block,
  mesh.send-channel-invite, conversations.list, conversations.messages.
* MeshState gains presence (pubkey → status+timestamps) and contacts
  (pubkey → ContactEntry{alias,notes,pinned,blocked}) in-memory stores.
* MeshService gains find_message_by_id (Forward lookup), apply_local_edit /
  apply_local_delete (optimistic local echo), and send_chunked_payload — an
  MC-framed base64 splitter that fires as a fallback inside send_typed_wire
  when wire > MAX_MESSAGE_LEN and no federation path is known. Reuses the
  existing receive-side reassembly in listener/decode.rs.
* Receive dispatch arms for PsbtHash, Presence, ChannelInvite, ReadReceipt
  (rolls forward `delivered` flag on own-Sent ≤ seq for that peer), Forward,
  Edit, Delete. Edit/Delete guard against cross-peer tampering by matching
  the target MessageKey pubkey against the sender's advertised pubkey_hex.
