Migrate src/filemanager/skin_dialog.rs::render() from the bespoke
Clear+Block shell (no shadow, square borders) to
terminal::popup::render_popup (rounded borders + MC-matching drop
shadow + centered layout).
This makes skin_dialog visually consistent with all 13 other TLC
dialogs that already use render_popup. The /tmp/5.png screenshot
(showing the skin selector without shadow) is now fixed — every
TLC dialog has identical premium chrome.
Deleted:
- Duplicate 'centered_rect' helper (replaced by popup::centered_percent_rect)
- Inline Block construction
- Manual Clear render
Added:
- render_drops_shadow_outside_popup test asserts the bottom-right
cell carries theme.shadow background (assertion of MC's
tty_draw_box_shadow algorithm at the dialog level).
Tests: 1112 passed (was 1111, +1).
