Refs #470 -- Adjusted Field.db_returning to be backend agnostic.

2025-08-23T16:09:43Z

Determining if a field is db_returning based on the default connection feature availability prevents the usage of RETURNING for db_default fields in setups where non-default backends do support RETURNING. Whether or not the field should be attempted to be returned is already checked at the compiler level which is backend aware.

Refs #36064 -- Added Model.has_db_default() to encapsulate NOT_PROVIDED checks.

2025-01-10T07:31:15Z

This avoids many awkward checks against NOT_PROVIDED and provides symmetry with Field.has_default() which is also the reason why it wasn't made a property.

Fixed #35982 -- Made DecimalField.get_db_prep_value() call DatabaseOperations.adapt_decimalfield_value().
