Summary

Add middleware that extracts tenant context from JWT tokens and enforces tenant-scoped access across all API endpoints.

Design

JWT middleware extracts user_id and tenant context from Authorization header
All downstream handlers receive tenant-scoped context
Unauthorized requests return 401
Cross-tenant access attempts return 403

Implementation Tasks

Implement JWT validation middleware
Add tenant context extraction from verified tokens
Inject tenant context into request handlers
Add authorization checks on all note endpoints
Return proper HTTP status codes (401 unauthenticated, 403 unauthorized)
Add middleware tests with valid/invalid/expired tokens

Security Considerations

Verify JWT signature on every request
Reject expired tokens
Ensure tenant context cannot be spoofed via headers
Log authentication failures for monitoring

Acceptance Criteria

All API endpoints require valid JWT
Tenant context is correctly extracted and enforced
Invalid/expired tokens return 401
Cross-tenant access returns 403
Middleware tests cover happy path and attack scenarios
