feat: add more e2e tests to frontend

[lucaseduoli]

This pull request introduces several updates to the project's Docker configuration and frontend dependencies. The main focus is on switching Docker services from using pre-built images to building them locally, and on adding new logging-related dependencies to the frontend.

Docker configuration changes:

• Switched all services in docker-compose.yml (opensearch, openrag-backend, openrag-frontend, langflow) from using pre-built images to building from local Dockerfiles, which will help with local development and debugging. [1] [2] [3] [4]
• Exposed port 8000 for the openrag-backend service to allow direct access during development.

Frontend dependency updates:

• Added the winston logging library and its dependencies (such as logform, winston-transport, triple-beam, etc.) to frontend/package-lock.json and as a dependency, enabling advanced logging capabilities in the frontend. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]
• Added various supporting libraries required by winston and its ecosystem, such as @colors/colors, @dabh/diagnostics, async, fecha, fn.name, inherits, kuler, one-time, readable-stream, safe-buffer, safe-stable-stringify, stack-trace, string_decoder, text-hex, and more. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15]

Other changes:

• Updated .dockerignore to also exclude frontend/tests/logs/ from Docker build context, preventing test logs from being sent to Docker.

Summary by CodeRabbit

• New Features

  • Expanded end-to-end coverage for chat, knowledge ingestion, document search, model switching, theme switching, and settings restore flows.
  • Added support for richer test scenarios around file uploads, URL ingestion, tasks, and knowledge filters.

• Bug Fixes

  • Improved reliability when switching models, restoring settings, and handling long or unusual chat inputs.
  • Strengthened checks for document ingestion, deletion, and search accuracy.

• Chores

  • Updated build and test configuration to better handle logs, sharded CI runs, and test reporting.

Walkthrough

This PR adds a Playwright end-to-end test harness for the frontend (page objects, fixtures, specs, test data), sharded CI execution with report merging, new dependencies (winston, zustand), and removes numerous debug console logs while adjusting several React useEffect/useCallback dependency arrays across app/component files.

Changes

Frontend Playwright test harness

Layer / File(s)	Summary
CI sharding and reporting .github/workflows/test-ci.yml, frontend/playwright.config.ts, .dockerignore, .gitignore, frontend/.gitignore	E2E tests run across 4 shards, upload shard-scoped artifacts, merge into a combined HTML report; Playwright uses blob reporter in CI; test logs are gitignored/dockerignored.
Shared test config and fixtures frontend/tests/config/*, frontend/tests/utils/*, frontend/package.json	Adds provider/test configuration, logging (winston), navigation/onboarding helpers, model-transition helper, and a Playwright fixture extension with page objects and document cleanup.
Chat, Knowledge, Settings, and TasksMenu page objects frontend/tests/pages/*	Implements reusable page objects for chat Q&A/streaming/theme/URL-ingestion, knowledge document/filter/chunk management, settings/provider configuration, and task-drawer status handling.
Chat, upload, and setup specs frontend/tests/core/00_setup.spec.ts, basic-questions.spec.ts, chat-nudges.spec.ts, theme-switching.spec.ts, fileUploadQA.spec.ts, model_switching.spec.ts, z_update_model_providers.spec.ts	Adds specs for onboarding setup, chat prompts/refusals, suggestion clicks, theme switching, file upload Q&A, and provider switching/transitions.
Ingestion, search, and knowledge-flow specs frontend/tests/core/*ingestion*.spec.ts, chunk-*, document_deletion.spec.ts, knowledge_filter.spec.ts, search.spec.ts, financial_document.spec.ts, restore_flow.spec.ts, tasks-menu.spec.ts, upload-and-query.spec.ts, picture_desc.spec.ts	Adds specs for bulk/diverse/URL ingestion, chunk size/overlap/search analysis, document deletion, knowledge filters, financial document Q&A, settings restore flow, task upload monitoring, and prompt-injection safety checks.
Test-data fixtures frontend/tests/test-data/**	Adds sample documents in supported/unsupported formats and bulk/combo ingestion fixtures for the above specs.
Runtime and component dependency updates frontend/app/**, frontend/components/**, frontend/contexts/**, frontend/hooks/**, frontend/lib/**	Removes debug console logging and adjusts several useEffect/useCallback dependency arrays in auth, chat, knowledge, onboarding, settings, and task-related code without changing core behavior.
