Add HACS integration, 8 Lovelace cards, and pairing page

New HA integration (integration/custom_components/luma_home/) with:
- WS API: luma/get_config (Lovelace→v2 bridge), luma/pair, luma/pair_status
- Config flow with dashboard URL path setting

8 HACS frontend cards (cards/) matching TV app visual spec:
- toggle, range, climate, media, curtain, action, vacuum, weather
- Glass card design: rgba(36,40,48,0.75) bg, 22px radius, accent glows

Pairing page (pairing/luma-pair.html) for TV token provisioning.
Web dashboard (web-dashboard/) — legacy config editor (deprecated).
