List view metadata columns and drag-to-resize everywhere

- New optional list-view columns: Description, Size (now includes
  directories), Modified, Owner, Created (via statx birth time), Content
  (item/line count or image dimensions), Access (rwx)
- Drag-to-resize: list view column headers, sidebar sections (Bookmarks/
  Devices/Filetree), Preview/Tags split, and the sidebar/preview side
  panels themselves — all commit to Config on release, not per drag frame
- Column resizing mutates existing row cells live instead of rebuilding,
  with metadata cached per (file, mtime) — fixes lag in large folders
- Fix list view background click (rows were full ListTile width with no
  empty space to click); bookmark selected-background now covers the
  triple-dot menu too; batch rename/new-file dialogs pre-select their
  default text instead of just pre-filling it
- Toolbar scrolls instead of clipping when buttons don't fit; toolbar and
  breadcrumbs are independently toggleable
- Add a "Server" bookmark icon
