Starters-on-pitch, chart movers sort, pre-filled what-if bracket, vs/@ fix

- Finished matches show the STARTING XIs on the pitch (red markers with
  the minute on everyone subbed off) with 'Subbed on' / 'Subbed off'
  lists below, minutes and ratings included; live matches keep the
  current-XI view that swaps substitutes in
- Title-race chart gets a sort toggle, defaulting to 'Biggest movers'
  (the teams whose odds changed most at the latest update — what's
  relevant now) with 'Title favorites' as the alternative
- Entering what-if on the bracket now pre-fills the model's most likely
  tournament: group slots seeded from win-group/advance odds (best-
  thirds assigned to their allowed slots via backtracking), every
  pairing picked by the model — a complete overview to edit by tapping;
  Reset returns to the projection
- Team fixtures drop the US 'vs/@' convention: always 'vs' plus an H/A
  badge with a tooltip
