Implementation for money data type

[kgodey]

Problem

Users will want to store monetary data in columns. We should allow them to do so and implement this type appropriately in the backend.

Proposed solution

Postgres has a built-in MONEY type, but the currency used for it is locked to the lc_monetary setting of the Postgres installation (see docs). We need to support storing money in different currencies in different columns, so we will create a custom MATHESAR_MONEY type.

Tasks that need to completed

• Design for money data type #239
• Update design for money data type options #655
• Backend work for Mathesar money custom type  #417
• Handle MONEY data type in the backend. #420
• Implement display options for the custom Money type #1105
• Implement filtering options for the money type #418
• Implement grouping options for money types #419
• Frontend implementation for Money Mathesar type #259
• Money type de#dates #1063
• Custom money type #1094

Moved to a later milestone:

• Support per-record currency types #656
• Frontend for multi-currency money type #657

Additional context

• Money type #118 architectural discussion
• Mapping DB data types to Mathesar data types #269

I'm going to close this meta issue since the one pending item: #419 is tracked separately.
