refactor: Move docker-compose files into Local Homelab/ directory

Restructures the project by moving all application-specific docker-compose.yml
files into a new `Local Homelab/` parent directory.

This change improves overall project organization and provides a clear
logical grouping for local homelab-related service configurations.

Affected files:
- `homeassistant/docker-compose.yml`
- `monitoring/docker-compose.yml`
- `teslamate/docker-compose.yml`

All are now located under `Local Homelab/<service>/docker-compose.yml`.

Local Homelab/monitoring/docker-compose.yml
