FEAT: add Platform API proxy with Elasticsearch and DynamoDB sync

- Add Platform API module to proxy requests to Platform API service
- Add Elasticsearch service for pipeline catalog sync (CRUD operations)
- Add DynamoDB service for storing pipeline tables/inputs configuration
- Sync pipeline creation/update/delete to Elasticsearch index
- Extract tables from jobs with connector-specific mappings:
  - JDBC: table_name, load_type, column_include_list, incremental_column_name
  - Singer: replication_method -> full_load/incremental
  - S3: same as Singer
- Map connector types to DynamoDB types (jdbc->database, singer->application, s3->file)
- Validate connector type is provided in job input
- Normalize pipeline IDs for Platform API (replace - with _), keep UUIDs for ES
