feat: store-and-forward radio protocol implementation (#708)

* feat: add optional blob field to WAKE and COMMAND messages

Implements protocol-level store-and-forward support (SF-2, SF-3):

- NodeMessage::Wake gains optional blob field (CBOR key 10) for
  piggybacked uplink data from send_async().
- GatewayMessage::Command gains optional blob field (CBOR key 10)
  for piggybacked downlink data on NOP commands only.
- Non-NOP commands ignore blob (key 10) per protocol.md section 5.2.
- Add get_bytes_optional() helper for decoding optional bstr fields.
- Add validation tests T-P120, T-P121, T-P122 (round-trip encoding,
  key absence verification, non-NOP blob rejection).
- Update all call sites across gateway, node, and test code with
  blob: None (construction) or blob: _ (pattern matching).

All 683 tests pass. Backward compatible: existing WAKE/COMMAND
messages without blob decode identically to before.

* feat: gateway store-and-forward support

Implements GW-0509 through GW-0512 and modifies GW-0102, GW-0103,
GW-0506 for the store-and-forward data channel:

handler.rs:
- DataReply gains delivery field (CBOR key 4, default 0).
  delivery=1 means deferred; delivery=0 means immediate.
- Encode omits key 4 when delivery=0 (backward compatible).

engine.rs:
- Add deferred_replies storage (HashMap<node_id, Vec<u8>>, RAM-only).
- handle_wake_core: extract WAKE blob, route to handler, store
  non-empty reply for NEXT cycle's COMMAND.
- handle_wake_core: inject stored deferred reply into NOP COMMAND
  blob, clear after delivery.
- handle_app_data_core: when handler replies with delivery=1 and
  non-empty data, store for deferred delivery instead of sending
  immediate APP_DATA_REPLY.
- Deferred data only delivered on NOP (non-NOP commands skip it).

All 683 tests pass across protocol, gateway, and node crates.
