• Add a unit test covering additionalProperties handling in GetResourceTypeSchema.

Hi @AkashKumar7902 , thank you so much for fixing this issue. Could you please add a before/ after screen shot of
rad resource-type show with this fix?

[AkashKumar7902]

@nithyatsu Pushed e978bef adding the requested tests:

• Test_GetResourceTypeSchema_Properties — covers the regular properties path (mix of required/non-required fields and a nested object).
• Test_getNestedSchema — directly exercises the new helper across all four branches: properties-present pass-through, descent into additionalProperties, neither-key fallback, and the precedence rule when both are set.

All four pass locally (go test ./pkg/cli/cmd/resourcetype/show/... -run Test_getNestedSchema -v).

For the before/after — I'll grab terminal output rather than screenshots since the issue is about textual output layout. Working on attaching that to a separate comment shortly.
