Fix: undrawn knockout fixtures block point scoring

[kilgor-trout-c22]

Problem

A wm2026 (Football World Cup 2026) competition showed finished games but never calculated points. Root cause: the data payload includes knockout-bracket fixtures whose teams aren't drawn yet (empty home_external_id/away_external_id). applyGame() recorded each as an error, so SyncReport::isSuccess() returned false, and the scoring guard if ($report->isSuccess() && $report->updated > 0) skipped scoreAllFinishedGames() for the whole competition — on every cron run and every Sync Results click.

Changes

• Skip undrawn knockout fixtures instead of erroring (HumHubApiAdapter::applyGame) — empty team IDs now count as skipped, keeping the sync report clean.
• Decouple scoring from sync success in all three sync paths (hourly/daily cron, live cron, Sync Results button) — scoring is idempotent, so a partial error no longer blocks scoring of cleanly-imported finished games.
• FWC 2026 setup now scores immediately (actionSetupWm2026) — runs scoreAllFinishedGames + matchday bonuses + special-bet auto-resolve, instead of leaving finished games unscored until the next cron.
• Log genuine failures — sync/save failures (flashReport, competition create, schedule auto-load, tip + special-bet save) now write to the kickoff app-log category, so issues are traceable when a flash toast isn't seen.

Notes

• module.json bumped to 1.0.8; CHANGELOG section added (still (Unreleased) — date stamped at release).
