For chats where we sent an opening message but the recipient never
accepted, /sync drops the room with no heroes and the recipient is
in state as m.room.member with membership:'invite' — not 'join'.
chat.reddit.com's web UI labels these rooms with the invitee anyway,
because it reads the full room state.
- roomToActiveChat now accepts 'invite' membership in addition to
'join' when scanning member-join state events.
- enrichUsernames pass 2 hits /_matrix/client/v3/rooms/{id}/state
first (cheap, returns all member events including invites) and
only falls back to /messages history if /state yields nothing.
- Added MatrixClient.getRoomFullState to back that lookup.
