Parse eight-digit decimal destinations as decimal.

If a user supplies 12345678, this branch sends to 0x12345678 instead of node 12345678. The numeric path does not check the node database, so it can send to the wrong node. Parse every prefix-less digit-only destination as decimal. Require ! or 0x for hexadecimal digits, and update the assertion at Line 467 in meshtastic/tests/test_mesh_interface.py. The PR objective specifies decimal parsing for prefix-less decimal inputs.

Review comment at @meshtastic/mesh_interface.py around lines 1009 - 1010:
Update the destinationId parsing branch so prefix-less digit-only values are
interpreted as decimal, and require an explicit ! or 0x prefix for hexadecimal
values; update the corresponding assertion in test_mesh_interface.py to expect
decimal parsing.

Stop sending when the node database is unavailable.

If parsing fails while self.nodes is empty, this branch only logs a warning. nodeNum remains zero, and _sendPacket continues with meshPacket.to = 0. Reject the unresolved destination as the nonempty-database branch does.

Review comment at @meshtastic/mesh_interface.py at line 1031:
In the empty-`self.nodes` branch of the parsing flow, reject the unresolved
destination instead of only logging a warning, so `_sendPacket` cannot continue
with `meshPacket.to` set to zero. Match the rejection behavior used by the
nonempty-database branch.
