[improve]: dynamically load options in Liferay component

### Improvement target

Liferay headless action loads and returns all available endpoints from the OpenAPI specification at once. For large Liferay applications this can result in slow options loading.

### Improvement description

Add .optionsLoadedDynamically(true) to the ENDPOINT property and use the searchText parameter in getEndpointsOptions(...) to support dynamic endpoint filtering. Current OpenAPI endpoint returns the complete specification document and does not support server-side endpoint filtering or search. To fully support dynamic loading, an additional backend endpoint would likely be needed to return filtered endpoints based on a search query instead of the entire OpenAPI specification.
