Functions dictGet and dictHas Use Current Database Name for DDL-Created Dictionaries

Why it matters

This feature fixes the issue where dictGet and dictHas functions did not correctly resolve dictionaries without an explicit database name, causing errors or unexpected behavior. By using the current database name implicitly, it simplifies dictionary usage and improves usability when working with dictionaries created via DDL.

How to use it

Users do not need to explicitly specify the database name when calling dictGet or dictHas on dictionaries created via DDL in the current database. The functions will automatically infer the current database context.
