feat/add MySQL and PostgreSQL data source connectors (#12817)

### What problem does this PR solve? This PR adds MySQL and PostgreSQL as data source connectors, allowing users to import data directly from relational databases into RAGFlow for RAG workflows. Many users store their knowledge in databases (product catalogs, documentation, FAQs, etc.) and currently have no way to sync this data into RAGFlow without exporting to files first. This feature lets them connect directly to their databases, run SQL queries, and automatically create documents from the results. Closes #763 Closes #11560 ### Type of change - [ ] Bug Fix (non-breaking change which fixes an issue) - [x] New Feature (non-breaking change which adds functionality) - [ ] Documentation Update - [ ] Refactoring - [ ] Performance Improvement - [ ] Other (please describe): ### What this PR does **New capabilities:** - Connect to MySQL and PostgreSQL databases - Run custom SQL queries to extract data - Map database columns to document content (vectorized) and metadata (searchable) - Support incremental sync using a timestamp column - Full frontend UI with connection form and tooltips **Files changed:** Backend: - `common/constants.py` - Added MYSQL/POSTGRESQL to FileSource enum - `common/data_source/config.py` - Added to DocumentSource enum - `common/data_source/rdbms_connector.py` - New connector (368 lines) - `common/data_source/__init__.py` - Exported the connector - `rag/svr/sync_data_source.py` - Added MySQL and PostgreSQL sync classes - `pyproject.toml` - Added mysql-connector-python dependency Frontend: - `web/src/pages/user-setting/data-source/constant/index.tsx` - Form fields - `web/src/locales/en.ts` - English translations - `web/src/assets/svg/data-source/mysql.svg` - MySQL icon - `web/src/assets/svg/data-source/postgresql.svg` - PostgreSQL icon ### Testing done Tested with MySQL 8.0 and PostgreSQL 16: - Connection validation works correctly - Full sync imports all query results as documents - Incremental sync only fetches rows updated since last sync - Custom SQL queries filter data as expected - Invalid credentials show clear error messages - Lint checks pass (`ruff check` returns no errors) --------- Co-authored-by: mkdev11 <YOUR_GITHUB_ID+MkDev11@users.noreply.github.com>
