tiviLux V18.3 — Instant Sports Loading

- Sports Hub paints from official NFL/MLB schedule + XUI titles first.
- SportsGamesToday TV/network enrichment runs after the page is already usable.
- Targeted local/network EPG matching runs last in the background.
- Third-party TV schedule delays can no longer block the Sports page.
- Preserves V18.2 league locks, V18.1 dedupe, numeric PPV sorting, and mobile fixes.
