feat: add Docker Compose profiles and Login Flow v2 service

Add selective service startup via Docker Compose profiles so each MCP
deployment mode runs independently. Also add the new mcp-login-flow
service (port 8004) for Login Flow v2 authentication (ADR-022).

Profile assignments:
- single-user: mcp (port 8000)
- multi-user-basic: mcp-multi-user-basic (port 8003)
- oauth: mcp-oauth (port 8001)
- keycloak: keycloak + mcp-keycloak (port 8002)
- login-flow: mcp-login-flow (port 8004)

Infrastructure services (db, redis, app, recipes) always start.

Integration tests cover the full Login Flow v2 provisioning flow:
OAuth → browser login → app password → Nextcloud API access for
notes, calendar, contacts, files, deck, and cookbook operations.
