fix(catalog): add local catalog file locations for entity discovery

Add local file locations to catalog configuration to enable automatic
discovery of local entities (catalog-info.yaml and examples/entities.yaml).
This ensures CI/CD, APIs, and Dependencies data are loaded into the catalog.

Without these local file locations, entities must be manually registered via
the Backstage UI, which explains why data appeared in backup but not in main.
