[Feature]: Containerize the application

**Is your feature request related to a problem? Please describe.**
Would be great to run the application via docker.

**Describe the solution you'd like**
A pre-built docker image should be available on hub / ghcr / etc.
Custom volumes to map local host folders to the container paths.
Work behind common reverse-proxies like caddy / nginx (for ssl certs, tls termination, etc), to access the web UI.
