fix(widget): refine layouts and progress UX across sizes

Compact (4×1)
- Reduce root vertical padding so the 4×1 cell yields ~56dp of content height.
- Make album art a true square (50×50dp) and center vertically; keeps edges
  clear of rounded corners.
- Tighten timing block: 2dp progress bar; 10sp labels with no extra font
  padding; prevents elapsed/total text from slipping below the background.
- Wrap album art in a 50×50dp FrameLayout with a new 6dp-radius background
  drawable; soft corners while remaining visually smaller than the widget body.
- Mirror the same structure in the preview layout so Studio preview matches
  on-device rendering.
  (app/src/main/res/layout/widget_layout_compact.xml,
   app/src/main/res/drawable/widget_album_art_bg.xml)

Large Short (4×2)
- Wrap album art in a fixed 90dp square container and enforce a true square
  crop via centerCrop.
- Tighten vertical spacing: thinner progress bar, closer timing row, controls
  shifted down for better balance.
- Keep album/timing text to the left of the controls but retune spacing so the
  stack stays fully inside the widget bounds.

Large (4×3 and up)
- Restructure to a vertical stack: header row (album art + text), full-width
  progress bar, timing row, primary controls, then secondary controls.
- Lock album art to a 150dp square; progress bar spans the widget beneath the
  header to match the new visual hierarchy.
