feat(config-settings): add path row event handling (Enter edit, LEFT clear, RIGHT no-op)

- Add __fish_user_dots_path as 8th entry in vars list
- Update panel_h from 14 to 16 (matches draw function's 16-line output)
- Clamp cur_row down to min(7, ...) to allow navigation to path row
- Add did_redraw flag (reset per iteration) to skip double-redraw after Enter
- Add Enter handler for row 7: erases panel, prompts for path, sets or clears
  __fish_user_dots_path universally, redraws, sets did_redraw
- Special-case RIGHT on row 7 as no-op (path is set via Enter only)
- Special-case LEFT on row 7 to clear path var via apply DEFAULT
- Add Enter key hint to --help navigation section
- Fix EXAMPLE block in __config_settings_draw docstring to include 8th arg
