Walkthrough

Modified the view properties handling in pgAdmin to include view columns SQL retrieval in materialized view SQL generation and to capture and propagate the view schema in two property fetch methods (_fetch_mview_properties and _fetch_properties).

Changes

Cohort / File(s)	Summary
View Schema and Columns SQL Enhancement web/pgadmin/browser/server_groups/servers/databases/schemas/views/__init__.py	Added retrieval of view columns SQL via get_columns_sql(did, vid) into materialized view SQL generation path. Captured view schema by assigning self.view_schema = result.get('schema') in both _fetch_mview_properties and _fetch_properties methods after result merge operations.
