vicrodh 12ed5a7c4a feat(slint): browser-like back/forward navigation history
Add a navigation history so pages can be walked back and forward.

- nav.rs: a back/forward stack of NavEntry (home, album, artist,
  settings); record() on fresh navigation, go_back/go_forward to walk it
- NavButtons: a [<] [>] pair styled like the Discover tab group; inline
  beside the Discover tabs and in place of the per-page Back button on
  album, artist and settings views
- All navigation routes through Rust (open-album/-artist record entries;
  the gear and header menu use NavState.request-settings) so the history
  stays accurate; back/forward re-apply entries, re-loading entity pages
- AppShell listens for the mouse back/forward buttons
- can-back / can-forward drive the buttons' enabled state

Also in this round:

- Album header description: render a pre-truncated short string so it
  wraps to a couple of lines instead of overflowing the header; the full
  text stays in the Read-more modal
- Header queue button uses an ordered-list icon (the previous one read
  as a playlist)

// Top header bar — navigation tabs anchored left, the user element
// anchored right, and the search field absolutely centered on the window.
//
// The search field is positioned at the true window center (not inside a
// layout column) so it stays centered regardless of how wide the tab row
// or the user element become.
//
// Responsive: below the first breakpoint the tabs drop their icons;
// below the second the search field narrows.
