fix(mesh): single-flight send + spinner + async federation POST

Browse Source 
Root cause of the "every bubble shows twice" complaint after the prior
dedup fix: the frontend was firing mesh.send twice per user action. A
held/repeating Enter key on the input fires a keydown per repeat, and
handleSendMessage didn't guard on mesh.sending, so both calls queued
through the store's sendQueue and both executed against the same
contact_id (backend logs show two mesh.send RPCs 13ms apart, same text).
That's why sender and receiver both saw doubles — the envelope actually
was transmitted twice.

Mesh.vue: handleSendMessage now early-returns if mesh.sending or
sendingArch is already set. Send button replaces the `...` placeholder
with a proper spinning ring (`.mesh-send-spinner`) so the held-Enter case
stops looking like the app is ignoring the user.

mesh/mod.rs: send_typed_wire_via_federation no longer blocks on the Tor
POST. Sent MeshMessage is recorded synchronously (UI bubble appears
instantly); the HTTP goes in tokio::spawn. Tor circuit setup was the
1–5s lag the user was seeing on every send to a federation peer. Delivery
failure still shows as `delivered: false` via the read-receipt path.
