Martin Dvorak 9d6ef90f02 Keep the library header steady across tabs; simplify the empty states
Header & action bar
- Import JSON no longer disappears on the Homework tab: it sits directly
  under the "Your icebox" header/subtitle, above the tab switcher, on every
  tab — so switching pools no longer shifts the layout or hides actions. It
  is one secondary button at all sizes now, not a quiet link when empty.
- The decks-only "Homework Solver" header action is gone; the homework tab's
  empty-state CTA and the drawer cover starting a new solve.

Empty states
- Dropped the "Using your own Ollama models — check the connection in
  Settings." line (and its two dictionary keys) everywhere.
- Both tabs share one structure: ice icon -> heading -> short description ->
  primary CTA button, starting at the same height:
    Study Decks: "No decks yet" -> "Freeze a page of notes into flashcards
    and quizzes." -> "Create study deck"
    Homework: "No homework yet" -> "Solved assignments and step-by-step
    guides show up here." -> "Solve homework"
- CTA labels read as actions on the standardized nouns; removed the now
  unused actionStudyDeck/actionHomework keys.

Tabs
- Link segments are 44px tall at every breakpoint (min-height in the base
  .segmented > a rule).

Service worker: freezmo-v11.

Verified: library-consistency suite 49/49 (Import visible with a fixed
position on both tabs, no Ollama text, empty states at the same y, primary
ice CTA buttons >=44px, deep links, deletion, redirects, desktop, 360px, axe
en+cs light+dark), mobile 51/51, i18n 27/27, desktop regression 74/74.
Lint + build clean.

/**
* Freezmo service worker (production only).
*
* Strategy, deliberately conservative:
* - API routes are never cached and never intercepted.
* - Navigations: network first, falling back to the cached shell, then /offline.
* - /_next/static + icons: stale-while-revalidate (fast, self-healing).
* - Everything else: straight to the network.
*
* Bumping CACHE_VERSION is how a new deploy invalidates old assets.
