refactor(settings): consolidate dataflowEnabled into enableIndexer

Remove duplicate dataflowEnabled setting and update all references to use
the existing enableIndexer setting. This eliminates confusion from having
two settings controlling the same indexer functionality.

Changes:
- Remove dataflowEnabled from TaskProgressBarSettings interface
- Remove dataflowEnabled from DEFAULT_SETTINGS
- Update IndexSettingsTab to use enableIndexer
- Update createDataflow.ts isDataflowEnabled() to check enableIndexer
- Update index.ts refresh commands to check enableIndexer
- Update McpServer.ts to check enableIndexer
