feat: hero card layout in all pills, cache-while-loading, logo splash screen

- Every pill (F1, Tech, AI, Cloud, HomeLab…) now shows the same hero card
  layout as "All" — first story is the big featured card, rest follow as rows
- "All" retains its full multi-section front page (US / Tech / AI / Sport…)
- Topic pill headers use the pill name instead of "TOP STORIES"
- filteredStories now falls back to cached SwiftData rows while loading, so
  switching to F1 or Tech shows cached cards instantly instead of a blank list
- Logo splash screen (3 pill bars + jarvis wordmark) shows on launch and fades
  out after setup completes; minimum 1.3 s so it's always readable
- JarvisWordmark moved to Theme.swift so SplashView and feed can share it
