feat: custom sidebar panel + deploy_automation service

SmartChain AI panel — sidebar page with two tabs:
- Generate Automation: describe in natural language → preview YAML → deploy
- Analyze Camera: select camera → enter prompt → get AI analysis

New service `smartchain.deploy_automation`:
- Accepts raw automation YAML
- Writes to .storage/automations + triggers reload
- Used by panel for deploying generated automations

Panel uses HA custom panel API (web component with hass object).
Registration is graceful — panel is skipped if frontend is unavailable.

128 tests (+3 new for deploy_automation service), lint clean.
