fix(settings): Remote nav now scrolls to the right section

The Remote Control nav item carried id: '@iptvnator/ui/remote-control'
— the NX library name pasted in place of the section's HTML id. The
settings-section-scroll directive resolves the target with
document.getElementById(), which returned null for that string, so
clicking "Remote" silently no-op'd. The active-state binding
([class.settings-group--active]="activeSection() === 'remote-control'")
also never lit up because the nav reported a different id than the
section template uses.

Change the nav id to 'remote-control' so it matches the section's
id="remote-control" attribute.

Added a focused regression spec (settings-options.spec.ts) that:
- asserts the desktop-only items light up only when isDesktop is true,
- reads each section component's root <section id="…"> at test time and
  cross-checks the nav id set against it, so any future drift between
  the two (renamed section, new section without nav entry, copy-paste
  of a library path into the id) fails the build.
