Fix vale warnings

What does this MR do and why?

Fix more vale warnings in files belonging to Group: Database

• fix gitlab.FutureTense
• escape SQL keywords
• add a few uppercase exceptions
• escape table names
• add ignore comment to direct quote from an issue

This is part 2 of many, the original MR was too big, sorry 😅

Uppercase exceptions:

• DML and DDL are from doc/development/database/migrations_for_multiple_databases.md line 23-24
