feat: Add type widening support to schema compatibility check

[OussamaSaoudi-db]

Please describe why this is necessary.

Type widening allows a column with a narrower type to be read with a schema that has a wider type. For example, data stored as u16 can be read as u32 with type widening.

Describe the functionality you are proposing.

Modify the schema compatibility check function in schema_compat.rs to handle this case.

Additional context

A useful function to look at is check_cast_compat which does the type widening logic for arrow types.
