Add glass card rendering and 6 card types for HA tab

Implement the full Home Assistant tab with room-based navigation
and glass-morphism card rendering:

- Toggle card: on/off for lights, switches, covers with state indicator
- Range card: dimmable lights with brightness bar and D-pad ±10% control
- Climate card: current/target temp, HVAC mode, D-pad ±0.5°C, sparkline
- Action card: one-shot activation for scenes and scripts
- Vacuum card: summary card that opens room selection modal
- Weather card: hero card with condition icon, temp, humidity, wind

Navigation: room tabs (horizontal pills), card grid (3-col), vacuum
modal with room multi-select, cleaning mode cycle, and start button.
Back button cascades: vacuum modal → card grid → room tabs → Home page.

Glass design: rgba(255,255,255,0.12) fill, 22px radius, 1px border at
0.15 opacity, elevated shadow on focus. Accent color #7EB8DA for active
entities, warm orange for heating, cool blue for cooling.

Wires Effect::Ha to dispatch toggle/brightness/temperature/scene/vacuum
service calls through ha_client. Adds 6 new SVG icons matching the
existing Lucide stroke style.
