feat(cortex): add Intake Blocks MVP for voice/text commands

Adds 4 new intents for intake workflow:
- intake_status: shows completion percentage and section checklist
- intake_navigeer: navigation to specific intake tabs
- risico_query: displays risk assessments with severity indicators
- diagnose_query: shows primary/secondary diagnoses

New components:
- IntakeStatusBlock, RisicoBlock, DiagnoseBlock
- Shared block components (BlockLoading, BlockError, BlockEmpty, BlockSection, BlockItem, BlockFooter)
- useBlockData and useIntakeContext hooks

New API routes:
- GET /api/cortex/intake/status
- GET /api/cortex/intake/risico
- GET /api/cortex/intake/diagnose
