A lot of our code is repeatedly testing if individual errors are specific types of Not Exist errors. This is repetitative and unnecesary. `Unwrap() error` provides a common way of labelling an error as a NotExist error and we can/should use this. This PR has chosen to use the common `io/fs` errors e.g. `fs.ErrNotExist` for our errors. This is in some ways not completely correct as these are not filesystem errors but it seems like a reasonable thing to do and would allow us to simplify a lot of our code to `errors.Is(err, fs.ErrNotExist)` instead of `package.IsErr...NotExist(err)` I am open to suggestions to use a different base error - perhaps `models/db.ErrNotExist` if that would be felt to be better.
