fix: hide Knowledge Ingestion component and rename Retrieval to Knowledge Base (#12054)

* fix: hide Knowledge Ingestion component and rename Retrieval to Knowledge Base

Move ingestion component to deactivated folder so it's excluded from
dynamic discovery. Rename KnowledgeRetrievalComponent to
KnowledgeBaseComponent with display_name "Knowledge Base". Update all
exports, component index, starter project, frontend sidebar filter,
and tests.

* fix: update test_ingestion import to use deactivated module path

* fix: skip deactivated KnowledgeIngestion test suite

* [autofix.ci] apply automated fixes

* fix: standardize formatting and indentation in StepperModal component
