fix: drop type_key column from text_fields and datetime_fields tables

[CyanVoxel]

Summary

This PR fixes #1367 by dropping the leftover type_key columns from the text_fields and datetime_fields tables. Because SQLite does not allow for the removal of columns with foreign key constraints, I've had to create new versions of these tables without the columns and copy the data from the old tables to the new ones, as outlined in the SQLite documentation.

I've also made a related change to enforce the ordering of columns inside of both of these tables. SQLAlchemy by default orders these columns strangely as it combines fields from the base fields definition, and I did not wish to canonize that ordering in raw SQL statements for the migration.
