chore(compose): add shared json-file logging config and component labels

Introduce x-logging anchor with json-file driver, size/file caps, and
container name tagging so Alloy on puck can reliably tail every service
through the Docker socket. Apply to all services and inject
MNEMOSYNE_COMPONENT env vars (init/app/mcp/worker) for consistent log
attribution both in Loki and via `docker logs`.

Also update mnemosyne_integration.md to reflect the shift from per-turn
JWTs to long-lived team JWTs for workspace-scoped MCP access.
