refactor: update knowledge document types and API client interfaces

- Refactored types in `Knowledge/types.ts` to introduce new interfaces for document handling.
- Added `KnowledgeDocItem`, `KnowledgeDocsListResponse`, `KnowledgeDocsUploadInput`, `KnowledgeDocsUploadResponse`, and `KnowledgeDocsDeleteResponse` for better structure and clarity.
- Updated `KnowledgeDocsApiClient` interface to include methods for listing, uploading, and deleting documents.

fix: replace deprecated icons in AccountSettingsPanel and SettingMenu

- Replaced `CheckCircleIcon` with `CheckCircle` from `lucide-react` in `AccountSettingsPanel.tsx`.
- Updated `SettingMenu.tsx` to use `Settings` and `User` from `lucide-react` instead of custom icons.

test: add tests for knowledge docs routes and KnowledgePage

- Created `knowledge-docs-routes.test.ts` to test API routes for listing, uploading, and deleting knowledge documents.
- Added `knowledge-page.test.tsx` to test the rendering and functionality of the KnowledgePage component, including document loading and deletion.
