Add MLS standings sync and fix simulator conference resolution (#423)
* Add MLS standings sync and fix simulator conference resolution

- New MlsStandingsAdapter using ESPN's free soccer API (no key required),
  returning Eastern/Western conference data, W/D/L/GF/GA/GD/PTS, conference
  rank, and home/away records; registered under mls_bracket
- Display route now shows soccer table columns and a 9-team playoff cutoff
  line for mls_bracket (top 9 per conference qualify for MLS Cup Playoffs)
- MLS simulator gains a third conference fallback: reads externalId="Eastern"
  or "Western" on the participant, mirroring the LLWS pool-assignment pattern
  so admins can bootstrap conference data before the first standings sync
- 9 unit tests covering stat mapping, conference normalization, rank ordering,
  and error paths

* Address code review feedback on MLS standings + simulator

1. Update mls-simulator.ts module comment to document the new step-3
   externalId fallback in the conference resolution order
2. Tighten normalizeConference to exact-match "Eastern"/"Western
   Conference" instead of broad substring, preventing false matches
   on names like "Northeast"
3. Pre-parse statsMap for each entry before the sort so it isn't
   rebuilt O(n log n) times during comparison
4. Document the externalId name-matching tradeoff on
   parseConferenceFromExternalId
5. Try ESPN's gamesPlayed stat before falling back to wins+losses+ties
   sum; export parseConferenceFromExternalId for direct testing
6. Add tests: normalizeConference passthrough, winPct=0 at preseason,
   and parseConferenceFromExternalId (case-insensitivity, null/undefined,
   numeric ESPN IDs, unrecognized strings)

* Fix lint: replace != null with !== null && !== undefined

oxlint enforces eqeqeq; the five != null checks in mls.ts were flagged.
