Fixes #882

I noticed during onboarding that even once documents were ingested the frontend continued to poll the backend for task status. This is unnecessary, keeps the backend server busy when it doesn't need to be and fills the logs with polling. This addition stops the onboarding cards from polling when they are completed.

I found the page at /admin, it appears to be an abandoned page for uploading files that has been superseded by /knowledge, so I removed it.

Fixes #818

Add end-to-end sync support for cloud connectors. Frontend: introduce useSyncConnector/useSyncAllConnectors hooks and wire sync buttons into the knowledge page and actions dropdown with pending state and toast feedback; invalidate search queries after sync. Backend: add get_synced_file_ids_for_connector and change connector_sync to only re-sync files already indexed in OpenSearch (prefer document_id, fallback to filename) to avoid reimporting deleted items; implement sync_all_connectors to batch-sync existing cloud connector files and emit telemetry. Infrastructure: expose DOCUMENT_ID and SOURCE_URL env vars in docker-compose and Helm values/templates and add them to LANGFLOW variables. Langflow flow: update flows/ingestion_flow.json to add secret inputs and dynamic document_id/source_url form fields and adjust node visibility/positions and defaults. This ensures targeted re-syncs of previously indexed cloud files and provides UI controls to trigger syncs.

Introduce OPENSEARCH_INDEX_NAME (default: documents) to .env.example and wire it into docker-compose so services (including Langflow) receive the index name; update the integration workflow to watch flows/**. Large documentation revisions: clarify onboarding/setup/prereqs, OAuth redirect URIs and webhook guidance, list supported ingestion file types, consolidate troubleshooting links, and reorganize/configure many environment and Langflow-related settings in the configuration reference. Also include multiple minor frontend/backend updates and add SharePoint utils and TUI startup checks to support connector/startup behavior.

Include allowed_users/allowed_groups in search results and frontend types/UI; update chunks page to display access control. Harden OpenSearch interactions: use filename.keyword in aggregations, safer _source access, and stronger logging. Add knn_vector mapping checks/handling to avoid known OpenSearch k-NN NullPointerException, verify dimensions, and skip or warn on mapping issues. Improve embedding generation with tenacity retries and exponential backoff, add IBM/watsonx rate-limit handling (sequential with delays), and better concurrency controls. Misc: hide long embedding vectors from _source, small logging and stability improvements throughout the multimodel OpenSearch component and search service.

Add support for document ACLs (allowed_users, allowed_groups) end-to-end: expose ALLOWED_USERS and ALLOWED_GROUPS env vars and include them in LANGFLOW_VARIABLES_TO_GET_FROM_ENVIRONMENT (docker-compose.yml); extend the ingestion flow UI to accept dynamic allowed_users/allowed_groups inputs and update node metadata/positions; normalize metadata in OpenSearch ingestion components so allowed_users/allowed_groups arriving as JSON strings are parsed into lists (flows/components/opensearch.py and flows/components/opensearch_multimodel.py). Also import (and comment) vector_store_connection in multimodel component, add/adjust raw_search/tool metadata and update related timestamps/code_hash. Minor frontend, connector, service and helm/value changes to propagate the new ACL fields and related defaults.

Update useSyncAllConnectors and useSyncConnector to remove the delayed setTimeout that invalidated the "search" query and instead immediately call queryClient.invalidateQueries({ queryKey: ["tasks"], exact: false }). This ensures new sync jobs show up in the task list right away instead of waiting for a delayed search refetch. (file: frontend/app/api/mutations/useSyncConnector.ts)
