BDMS 57: well screen & other updates

[jacob-a-brown]

Why

This PR addresses the following problem / context:

• WellScreen should have nma_pk_wellscreens to enable an audit of the data transfer
• type annotations should not set nullability. That should be explicitly set in mapped_column(...)
• Pydantic should be used to validate data

How

Implementation summary - the following was changed / added / removed:

• Added nma_pk_wellscreens to WellScreen table to enable transfer audits
• Used type annotations to set the type, but not nullability. That is now set as nullable=True or nullable=False in mapped_column(...)
• Pydantic is now used to validate contact transfer data
• Because nma_pk_wellscreens are not part of the Pydantic model/schema well screens are now added explicitly with the session instead of with model_adder

Notes

Any special considerations, workarounds, or follow-up work to note?

• The type that's hinted at in Mapped[<type?>] is what SQL Alchemy uses. It does not need to be set in mapped_column(...). To set the string length, however, String(<length>) must be used in mapped_column(...).
