agatha 602648ef56 Feat: Gate API docs endpoints behind API_DOCS_ENABLED env var
When API_DOCS_ENABLED=false, FastAPI registers no routes for /docs,
/redoc, or /openapi.json, returning 404 for all three. Default is true
for backwards compatibility. Invalid values fall back to true (FR-007).

Fix: Remove tests/ and alembic/ from api/.dockerignore so the test
Dockerfile (which uses COPY . .) includes the test suite; Dockerfile.prod
is unaffected as it only copies app/ explicitly.

# Contract: API Documentation Endpoints
These three endpoints exist in FastAPI by default. This feature makes their availability conditional on a runtime configuration flag.
## Affected Endpoints
| Endpoint | Default path | Purpose |
|----------|-------------|---------|
| Swagger UI | `GET /docs` | Interactive browser-based API documentation |
| ReDoc UI | `GET /redoc` | Alternative read-only API documentation |
| OpenAPI schema | `GET /openapi.json` | Raw JSON schema of the entire API surface |
## Behaviour by Flag State
### `API_DOCS_ENABLED=true` (default)
All three endpoints respond exactly as they did before this feature. No change.
| Endpoint | Response |
|----------|----------|
| `GET /docs` | `200 OK` — Swagger UI HTML |
| `GET /redoc` | `200 OK` — ReDoc UI HTML |
| `GET /openapi.json` | `200 OK` — OpenAPI schema JSON |
### `API_DOCS_ENABLED=false`
All three endpoints are unregistered. Requests fall through to the framework's default 404 handler.
| Endpoint | Response |
|----------|----------|
| `GET /docs` | `404 Not Found` |
| `GET /redoc` | `404 Not Found` |
| `GET /openapi.json` | `404 Not Found` |
## Invariants
- All other endpoints are unaffected in both flag states.
- The `GET /api/v1/health` endpoint always returns `200 OK` regardless of the flag.
- Internal OpenAPI schema generation (used for request/response validation) is not disabled — only the HTTP routes serving it are removed.
- The flag is read once at application startup. A running process does not respond to live changes; a restart is required.
