CydandClaude Fable 5 4b25f89e6f Football: every player picks their own team and position 
Closes the gap left by the football commit. Members publish their
picks as lobby member data (tm/ps) alongside their loadout, and the
owner publishes the scenario (sc) so members know when the picks
matter. The lobby room turns into a team sheet: each member row shows
their team and position, and MY TEAM / MY POSITION buttons cycle the
local pick and republish it live, so everyone watches the sides fill
out before the host launches.

The egg builder honors explicit picks and only fills gaps:
- pilots who chose a team get it; the rest are spread across the
  host team and one other so the sides stay balanced
- a team with no volunteer runner promotes its first UNPICKED member,
  never overriding someone who chose crusher or blocker
- if two pilots on a team both claim runner, the first keeps it and
  the second lines up
- colors stay derived: runner in the team runner color, everyone else
  in the team color

Verified: a three-pilot egg puts the host on crusher in team color
with an unpicked teammate promoted to runner in runner color, the
other side gets its own runner, and the teams/pilots blocks group
correctly; the lobby room cycles picks and repaints the roster; both
scenarios still pass their single-player regressions.
