Group sends built the recipient list from the full group membership, so
members already known to be unregistered were retried on every send via
the legacy 1:1 fan-out. On large groups this made a single send take
tens of seconds and could time out, leaving the message undelivered.
Filter out recipients whose unregistered timestamp is set before
sending, returning an unregisteredFailure result for each (so callers
and CLI output are unchanged) without the network attempt. The flag is
maintained independently by profile/CDS discovery and is cleared when a
recipient registers again, so skipped recipients are re-included
automatically.

Without an initial flush(), the JVM HttpServer buffers all
output until the first flush() in the 15-second keep-alive loop.
Clients with shorter timeouts (e.g. 10 s) abort before receiving
any data.
Add a flush() call directly after creating ServerSentEventSender,
before the wait loop, so the HTTP 200 response and headers reach the
client immediately upon connection.
Adds regression test SseInitialFlushTest that verifies at least one
byte arrives within 2 seconds of connecting to GET /api/v1/events.
When filling or updating a V2 group, profile keys were copied from
DecryptedGroup.members into the local profile store but not from
requestingMembers. Admins who never had a prior session with a user in
the join queue then lacked profile keys and could not decrypt profiles
(e.g. for listContacts).
Also process DecryptedRequestingMember entries the same way as full
members, using DecryptedMember / DecryptedRequestingMember types so the
lib module does not require a direct protobuf dependency.
