admin 078ed376eb feat(backend): implement 7-MVP FastAPI backend with all models and API stubs
Implements complete FastAPI backend infrastructure for MoreThanADiagnosis with:

Core Infrastructure:
- FastAPI application with CORS, error handling, health checks
- SQLAlchemy ORM with PostgreSQL support
- Pydantic configuration management
- Docker & Docker Compose for production deployment

Database Models (7 MVPs + Auth):
- User, Profile, Role, Consent (identity)
- RefreshToken, AuthAuditLog (authentication)
- ForumCategory, ForumThread, ForumPost, ForumReaction, ForumReport (forum)
- BlogPost (blog)
- PodcastEpisode (podcast)
- Resource (resources)
- TributeEntry (tribute)
- MerchProduct, Order, OrderItem (merch)

API Endpoints (Alphabetical MVPs):
- /api/v1/blog - Blog posts (list, get)
- /api/v1/forum - Categories, threads, posts, reactions, reports
- /api/v1/merch - Products, orders
- /api/v1/podcast - Episodes
- /api/v1/profiles - User profiles
- /api/v1/resources - Knowledge base
- /api/v1/tribute - Memorials
- /api/v1/health - Health checks

Configuration & Deployment:
- .env.example for configuration
- Dockerfile with multi-stage build
- docker-compose.yml for PostgreSQL + Redis + API
- Production-ready on nexus-vector with port 8000
- Non-root user, health checks, security best practices

Dependencies:
- FastAPI, SQLAlchemy, Pydantic
- PostgreSQL, Redis
- Testing (pytest), Security (passlib, python-jose)
- Full requirements.txt with 30+ packages

Status: Foundation complete, MVP endpoint stubs ready
Next: Database migrations, authentication implementation
