fix(ui): mobile layout overflows across admin, reader, and book pages

Every fix is a minimal class-level change; desktop layouts are untouched
because each fixed row already fit on one line there.

- progress: CFI string is one unbreakable token — it inflated the page
  layout width to 398-501px (whole-page zoom-out on phones) and rendered
  debug-looking text edge to edge. min-w-0 + break-all lets it wrap.
- audio reader: settings strip min-content (~470px) exceeded the 390px
  viewport, clipping Skip/Sleep and — because the page ICB inflated —
  pushing the chapters drawer (w-full of the viewport) past the screen
  edge so its timestamps clipped too. flex-wrap fixes both symptoms.
- book detail edit-metadata modal footer: Rescan/Reset/Write-to-file row
  overflowed the modal; clipped buttons were unreachable. flex-wrap.
- bookshelf save-filter modal footer: three buttons overflowed both
  screen edges. flex-wrap.
- admin libraries: rows overprinted (badge chips shrink-0 vs actions
  shrink-0, no wrap) — 'manga⟳Scan▸1 folders⌄Manage'. flex-wrap stacks
  actions under the name on phones.
- admin podcasts: maintenance table forced a 892px page (44% zoom).
  overflow-x-auto on the card scrolls the table inside it instead.
- stats: 4-pill range row forced 421px; page permanently ~7% zoomed out.
  flex-wrap.
- podcast feed detail: label+select pairs now travel in their own flex
  pairs so flex-wrap can never split 'Order' from its select; ids and
  htmx change-triggers preserved.
- cosmetics: conflicts stat labels tracking-wide→normal (UNRESOLVED
  clipped), archived file path line-clamp-3, rules-page Smart badge
  wraps cleanly, dashboard View All shrink-0 nowrap (was wrapping to
  two lines).
