feat: add disk usage bars to side panel and computer:// view

Browse source 
Side panel devices show a thin progress bar below each drive name,
proportional to disk usage. Bar turns red when usage exceeds 90%.
The computer:// icon view also shows usage bars under volume names.

New files:
- thunar-shortcuts-progress-renderer.c/.h: custom cell renderer
  (extends GtkCellRendererText) that draws text + usage bar

Modified:
- thunar-shortcuts-model: added USAGE_PERCENT column
- thunar-shortcuts-view: uses progress renderer instead of plain text
- thunar-text-renderer: added usage-percent property with bar drawing
- thunar-standard-view: sets usage-percent via cell_data_func for
  computer:// entries using thunar_g_file_get_free_space()
