Until now an incoming large message was invisible until every part landed.
ChatService::pendingLargeMessages() exposes the in-progress tier-3 receives
(conversation, chunks gathered / chunks needed) from the reassembly buffer, and
the chat tab renders a subtle centred line below the thread — "Receiving a large
message… 24 / 36 parts" — that updates each scan and disappears when the message
completes and surfaces as an ordinary bubble. A complete-but-withheld (sensitive
vault locked) group is not reported as incoming.
New string chat_receiving_large (English; 8 locales fall back). Unit test extended:
after the first slice the receive is reported in progress; after the whole message
arrives it is no longer pending.
