Remove MicroLink branding from website and setup script

- Remove MicroLink nav link and footer attribution from both HTML pages
- Replace MicroLink references with generic 'firmware' / 'Tailscale library'
- Remove the clone-MicroLink step from docs (now vendored in-repo)
- Update setup.sh to check vendored microlink/ dir instead of ../microlink
