feat: add heading-link-separator setting and UI support

Introduce a new setting `headingLinkSeparator (default '#')
customize the separator used between filename and heading when the
"Use heading as display text" option is disabled.

- Add `headingLinkSeparator` to settings type and defaults.
- Add localization keys and translations (en/zh/zh-TW) for the new
  setting and its description.
- Update settings UI to render a text input for the separator and
  re-render when "use heading as display text" toggles so the control
  shows/hides correctly.
- Use the configured separator when composing display text for heading
  links.
- Simplify a Wiki-link conditional to avoid redundant `useHeadingAsDisplayText`
  check when filename equals selected heading.

This allows users to customize the filename-heading delimiter for copied
heading links.
