Update container documentation to reflect disk space adjustments and Docker log management

Expand the root disk size from 35 GB to 50 GB and implement log size limits for Docker containers. Add details about the new monitoring dashboard for homelab services, including deployment instructions and access URL. Ensure clarity on log rotation policies and risks associated with disk space usage.
