web-player: app chrome (layout, navigation, player)

PlayerExtras is merged into PlayerBar, which now renders volume and
the queue button inline and uses the new Slider (a real range input
with thumb thickness controlled via CSS variables) for both the
progress bar and volume, replacing SeekBar and VolumeControl (grep
confirmed SeekBar's `compact` mode was dead code).

Sidebar and TabsBar migrate to appNavLinks(user, counts?), removing
the duplicated nav links between the two. Decision made without
blocking: Sidebar gains the gradient Logo mark it didn't have before,
for visual consistency with MobileHeader and the login screen.

PlayerDock and MobileHeader's z-index is fixed to z-(--z-sticky)
(they're fixed bars, not menus), and SegmentedControl's to
z-(--z-raised), per the plan's note B.1.5. glass-bar and
theme-transition are applied to PlayerBar (both variants), TabsBar,
Queue and Home (hero/spotlight), replacing duplicated
blur/transition styles.

Verified with npm run check (0 errors) and npm run build; smoke-tested
/login with no console errors. No authenticated visual QA (Docker
unavailable this session).

Upload usa ImageDropzone con `onselect` (prop nueva) y se envuelve en `{#key}` para poder resetear tras publicar — Δ: el contenedor de portada pasa de 144/176px (móvil/desktop) a 144px fijo (size-cover-hero, sin variante desktop mayor), y el icono de posición vacía de 64px a 36px (icon-xl), tal como recomienda el plan.
