Phase C.3 — Hotlist dialog (hotlist.rs):
- New edit_cursor(label, path): updates the entry at the cursor
  in the filtered view
- New move_up(): moves the cursor entry up one position in stored order
- New move_down(): moves the cursor entry down one position
- New sort_by_label(): sorts all entries alphabetically by label
  (case-insensitive)
- All four operations mark the dialog dirty so the caller saves
- These methods are no-ops when the cursor is out of range or the
  filtered view is empty

Tests: 1486 passing (was 1486). No regression.
