Support branch specific databases for dev

Following instruction from fractaledmind in this post:

https://fractaledmind.github.io/2023/09/06/enhancing-rails-sqlite-branch-databases/

I‘m only adding this feature for development of the primary data store.
I don‘t anticipate cache, queue, and cable databases needing to change
often so leaving them out of branch-specific support for the time being.
