Add dashed border style

Browse Source 
New --border=dashed / --list-border=dashed / --header-border=dashed etc.
Uses U+2576 (╶) for horizontal edges and U+2506 (┆) for verticals, with
rounded corners (╭╮╰╯) and sharp T-junction mids (├┤). Terminal cells
are taller than wide (~2:1), so horizontals use a sparse stub per cell
while verticals need more dashes per cell to look evenly dashed.
Works with inline sections.

- `--header-label` and `--footer-label` render on their respective separator row.
- The separator inherits `--color list-border` when the section's own border color is not explicitly set.
- `inline` takes precedence over `--header-first`: the inline section stays inside the list frame. `--header-border=inline` requires `--header-lines-border` to be `inline` or unset.
- New `dashed` border style with dashed edges (`╶` / `┆`) and rounded corners.
- `--border=dashed`, `--list-border=dashed`, etc.
- Works with inline sections (T-junctions render correctly).
- [vim] Move and resize popup window when detecting `VimResized` event (#4778) (@Vulcalien)
- Bug fixes
- Fixed gutter display in `--style=minimal`
