feat!: complete rehaul - implement dynamic node configuration system

BREAKING CHANGE: Transform static node monitoring into flexible ConfigMap-based
architecture with hot-reload capabilities and comprehensive management tools.

Major changes:
- Replace hardcoded nodes (virt1, virt2, virt3) with ConfigMap definitions
- Add configuration management CLI (config-manager.sh)
- Implement hot-reload configuration without restarts
- Enhanced web interface with rich metadata support
- New deployment scripts for streamlined setup
- Fix semantic versioning pipeline robustness

Infrastructure updates:
- ConfigMap integration in webserver deployment
- Custom nginx configuration for config endpoint
- Namespace-aware deployment (sensordash)
- Backward compatibility with existing sensor data files

This complete rehaul establishes the foundation for a professional,
enterprise-ready monitoring solution with full configuration flexibility.

Breaking changes require new deployment process using ConfigMap setup.
