feat(fusion_clock): premium glass NFC kiosk + scope CSS to kiosk page

Visual rewrite of the NFC kiosk page:
- Animated mesh gradient background (drifts on a 28s loop)
- Glass-panel state cards with backdrop-filter blur
- Animated SVG NFC icon (concentric waves emanate from a chip)
- Company logo pulled from res.company.logo, displayed in header
- Dominant-hue extraction from logo sets --nfc-h CSS var; entire
  palette interpolates from that one HSL hue
- Success burst (green glow + scale), error shake, smooth state fades
- Reduced-motion fallback respects prefers-reduced-motion
- Glass numpad + employee picker in Enroll Mode

CRITICAL FIX: scoped all kiosk styles under :has(#nfc_kiosk_root) so
they no longer leak into other frontend pages. Previous version applied
html/body overflow:hidden + display:none on header/footer globally,
breaking website scrolling and chrome on every frontend page.
