Look at using HTMX on frontend

[madeinoz67]

HTMX is a lightweight dynamic frontend framework https://htmx.org/ that will fit the majority of our UI needs without the complexity of other frontend frameworks.

We should be able to utilise this instead of having to implement data tables and associated api as raised in issues #54 and #55

This can be implemented in the current templates without having backend data finished, i.e. use dummy data data from the service layer
