fix: 2023 room instances, publish, role permissions and co-owner invites

- Room roles: list the creator as Creator (255), not CoOwner (30). The
  client takes the local role from the Roles list and only lets a player
  edit roles below their own (Creator excepted), so the creator could not
  edit Co-Owner and Creator permissions. Enforce the role ladder on the
  server (RoomRoleRules), let invitees accept (PUT roles/{me} role=30) and
  reject (PUT roles/{me}/invite role=0), send message Types 62/60/61, and
  push RoomUpdate after every role change.
- Permissions: persist PUT subrooms/{sub}/permissions cells in a new
  RoomRolePermissions table, serve them from photon_access_token (plus a
  roomserver/ twin) and push PhotonAccessToken to the sub-room.
- Publish: player-owned rooms are never IsRRO on the wire; the client
  hides Publish and every room setting for an RRO.
- Sub-rooms: wire SubRoomId = OrderIndex + 1 (the client will not load a
  sub-room with id 0), new rooms always get a named Home sub-room, and a
  startup pass repairs rooms without one.
- Instance browser: per-room Redis presence index, live players only,
  private instances for the people allowed in, real IsFull.
- Room/sub-room settings: creator or accepted co-owner everywhere.
