feat(mission): wire Tier 1 emits — rank/free/challenge match events

Adds IMissionProgressService to RankBattle, FreeBattle, ArenaTwoPickBattle, and
ArenaTwoPick controllers. Each finish handler emits the appropriate
MissionEventKeys builder result:

- RankBattle.Finish (win) → Ranked.WinAll(classId)
  Includes AI-rank routes; on a private server AI wins count the same.
- FreeBattle.Finish (win) → Free.WinAll() (aggregates only)
- ArenaTwoPickBattle.Finish → Challenge.MatchPlayAll or MatchWinAll
  Always fires challenge_play; wins additionally fire challenge_win and
  the ranked/arena/daily aggregates.
- ArenaTwoPick.Finish (5-win full clear) → Challenge.FullClearAll
  Gated on RunFinishOutcome.WasFullClear from the previous commit.

This closes six of the eight remaining catalog wire-up gaps; class_level_up
and rank_achieved follow in Tier 2 (need pre-state detection).
