Trino: Mount catalog files individually to preserve built-in catalogs

Address feedback from ebyhr on PR apache#2220 discussion r2583421945.

Instead of mounting the entire catalog directory, mount individual
catalog property files. This allows Trino to preserve its built-in
catalogs (memory, TPCH) which are helpful during development, while
still providing our custom Iceberg catalogs.

Mounted files:
- warehouse_rest.properties - REST catalog configuration
- warehouse_hive.properties - Hive catalog configuration
- config.properties - Trino server configuration
