This commit adds 6 new MCP tools to support Dataplex Data Profile,
Data Discovery, and Data Quality workflows, completely integrated
using standard gRPC client connections:
- generate_data_profile / get_data_profile
- generate_data_discovery / get_data_discovery
- generate_data_quality / get_data_quality

It also reuses get_operation and get_run_status to track these scans,
and refactors GetDataInsights to a generic GetDataScan method.

This commit addresses reviewer feedback for the Dataplex enrichment workflow:
1. Moves the 'enrich' toolset configuration block to the bottom of dataplex.yaml.
2. Adds documentation pages (markdown files) under docs/en/integrations/knowledge-catalog/tools/ for all 10 newly introduced/modified Dataplex tools.
3. Updates dataplex_integration_test.go to register the new tools, verify parameters of get endpoints, and implements runDataplexDataScanLifecycleIntegrationTest to verify the asynchronous scan creation, LRO polling (get_operation), job run checking (get_run_status), and scan result retrieving (get_data_profile) end-to-end.

This commit registers and adds complete end-to-end lifecycle integration tests for:
- generate_data_insights / get_data_insights
- discover_metadata / get_discovery_results
- check_data_quality / get_data_quality_results

This covers all 10 newly introduced Dataplex tools in the integration test suite.

This refactors the remaining 10 Dataplex write tools (checkdataquality, discovermetadata, generatedatainsights, generatedataprofile, getdatainsights, getdataprofile, getdataqualityresults, getdiscoveryresults, getoperation, getrunstatus) to match the new BaseTool framework design, and fixes the configuration initialization in their corresponding unit test files.
