fix: patch command injection, missing rate limit, Docker build, logger crash

- Sanitize session ID in control route to prevent command injection
via unsanitized URL params interpolated into shell commands
- Add mutationLimiter and structured logging to session control endpoint
- Install python3/make/g++ in Dockerfile deps stage for better-sqlite3
native addon compilation
- Handle missing public/ directory in Docker COPY with glob pattern
- Guard pino-pretty transport against missing devDependency at runtime
