Closes: #18588: Relabel Service model to Application Service

Updates the `verbose_name` of the `Service` and `ServiceTemplate` models to "Application Service" and
"Application Service Template" respectively. This serves as the foundational change for relabeling
the model throughout the user interface to reduce ambiguity.

To preserve backward compatibility for the REST and GraphQL APIs, the test suites have been updated
to assert the stability of the original field and parameter names. This includes:

*   Using `filter_name_map` in the filterset test case to ensure API query parameters remain
    `service` and `service_id`.
*   Employing the GraphQL test suite's aliasing mechanism to ensure the public schema remains
    unchanged despite the underlying `verbose_name` modification.

Subsequent commits will address UI-specific labels in navigation, tables, forms, and templates.
