Handle MONEY data type in the backend.

[kgodey]

This issue is to ensure that Mathesar can handle the Postgres MONEY data type.

As part of this issue, we need to ensure that:

• Users can use the API to change a column to MONEY if it's possible to do so.
• Automatic type inference during file import suggests MONEY when the MATHESAR_MONEY type is not installed and the currency detected matches the Postgres lc_monetary setting.

Additional Context

• Blocked by Backend work for Mathesar money custom type  #417
• See PR Extend the v0/databases/'s types list to show both Mathesar and DB type information. #368 for code that calculates which types are allowed for a column.
• Mapping DB data types to Mathesar data types #269

To double-check my understanding, we should expect a currency symbol to infer a column should be a MONEY type, correct?

@mathemancer Yes.
