feat(gcp): add GCP integration config, types, and page wiring

Adds the GCP integration tile, config types, region constants, account
DTO mapping, and routes the 'gcp' integration id to the shared
CloudIntegration page. Accounts list, service details, and account
removal work for GCP; the add-account and edit-account drawers land in
follow-up commits (their buttons are no-ops for GCP in this commit).

Also narrows Azure config checks by 'resource_groups' instead of
'deployment_region', since the GCP config in the widened
CloudAccount.config union also has a deployment_region field.
