* Deliver locally-generated replies addressed to us to the phone
Config get/set from the phone times out on every device: the client sends an
admin request, the node handles it, and the response is silently dropped
before it reaches the phone queue.
#10967 changed Router::sendLocal's isToUs branch from enqueueReceivedMessage()
to handleReceived(p, src), so a local packet keeps its RxSource instead of
being relabeled RX_SRC_RADIO by the queue round-trip. That is the right call
for the new policy gates, but module replies go out through
MeshService::sendToMesh() with the default RX_SRC_LOCAL, and a reply to a
phone-originated request is addressed to our own node (setReplyTo resolves
from == 0 to ourNodeNum). Those replies now re-enter callModules as
RX_SRC_LOCAL, where the loopback gate skips every module whose loopbackOk is
false - including RoutingModule, whose promiscuous sniff is the only path that
moves a received packet into toPhoneQueue. The reply is released, never sent.
Requests still work, because the phone's own packets arrive as RX_SRC_USER and
pass the gate, so a set_config is applied and only its acknowledgement is lost.
That is why a client can connect and download config but times out on every
config screen and every setter.
Deliver the phone's copy from sendToMesh() instead: for a local packet
addressed to us, the loopback gate is doing its job in keeping the packet away
from module re-dispatch, and the phone copy is exactly what is missing. Setting
loopbackOk on RoutingModule would instead echo every locally-generated
broadcast back to the phone, and relabeling replies RX_SRC_RADIO would undo the
origin separation #10967 added.
Also stop reporting ERRNO_SHOULD_RELEASE (35) to the phone in the QueueStatus
for these packets. It means "caller frees", not a send failure, and the same
hunk changed it from the 0 the phone used to see.
* Address review: trim comments, assert the QueueStatus count
Condense the added comments to the one-or-two-line house style; the rationale
lives in the commit message and PR.
The reply test drained QueueStatus records in a while loop, which would have
passed just as happily on an empty queue. Count them and require both the
request's and the reply's.
