Refactor cardamon

[ohuu]

Q1. It seems that we need to move functions for fetching UI stuff from the db out of the DAO and into their own classes

At the moment there are a load of functions in the DAOs which seem very specific to the UI. These will never be used by the DAOs so they should probably need to be moved to UI server which means the UI server should have access to the SqlitePool rather than the LocalDAOService

Q2. We probably need to batch saving metrics (both locally and remote) so we don't spam the db or network.

I think metrics are saved one at a time at the moment which we can probably get away with locally but probably not when saving to the remote server

[ohuu]

This is basically done I just need to merge all this back into main
