[BUG/Enhancement] Enforce unique object identifiers for users, instruments, projects, other

[GitBytes]

Database object IDs are currently able to be deployed in a number of fashions which allow for custom setups but don't lend themselves well to integrating with other Pacifica instantiations. This issue also hampers a clean unique id structure when it comes to adding projects, instruments, and users to the metadata schema.

The use of some other unique id structure, maybe uuid, or some other method should be considered as a way to maintain the uniqueness of all objects in the database.
