Show the host mission setup in both lobbies, and the VTV in football

The room told you who was in it and nothing about what you were about to
fly into. Only the owner's menu decides the mission, so nobody else could
see the track or the conditions until the race had already started.

The owner now publishes its picks as lobby data (track, time of day,
weather, game length) and the room draws them under the title: the track
on its own line, the conditions under it. Published as display names
rather than catalog keys, because the map list differs between race and
football and resolving it at the source saves the room from knowing
which table a key came from.

Football also names the VTV now. The team sheet was team and position
only, but the vehicle still decides how someone plays the position, and
it was already travelling as member data, just never drawn. Both roster
rows now run keys back through the catalogs, so nobody reads bttlbrg
where Battle Barge belongs, and the rows widened from the middle half to
two thirds to carry three fields.

The setup lines are only taken if they fit. Buttons are laid out upward
from the bottom edge while the roster runs down from the top, so on a
short window the two extra lines would have pushed the roster into MY
TEAM. The room measures the gap first and takes two lines, one, or none.
Checked against every window size from 3440x1440 down to 640x400 in both
scenarios.

Verified live on a hosted lobby. Race shows the track, the conditions
line, and Battle Barge / Red. Football shows the same setup with Battle
Barge, Blue / Aqua, Crusher, tracking the MY TEAM and MY POSITION
buttons as they cycle.
