Subject: [PATCH] fix(azure_ai): resolve api_base from env var in
 get_complete_url for Document Intelligence OCR

validate_environment() resolved AZURE_DOCUMENT_INTELLIGENCE_ENDPOINT
from the env var but only returned headers. get_complete_url() still
received None and raised ValueError. Now get_complete_url() also
resolves the env var as a fallback.

Fixes #21034
