fix(gitlab): add missing repos scope in project_mapping (#8743)

GitLab's makeScopeV200 did not create a repos scope when
scopeConfig.Entities was empty or only contained CROSS. This
caused project_mapping to have no table='repos' row, breaking
downstream DORA metrics, PR-issue linking, and all PR dashboard
panels that join on project_mapping.

The fix aligns GitLab with the GitHub plugin by:
1. Defaulting empty entities to plugin.DOMAIN_TYPES
2. Adding DOMAIN_TYPE_CROSS to the repo scope condition

Closes #8742
