#3214 Bugfix: Fix incomplete display of tenant resources page after window resize

[Copilot]

Pull request overview

This PR reorganizes frontend components by moving non-shadcn UI components out of components/ui into components/common, and updates all consuming imports accordingly. This helps keep components/ui reserved for shadcn-style primitives while housing app-specific widgets/renderers under common.

Changes:

• Added non-shadcn components under frontend/components/common (e.g., PdfViewer, Diagram, CopyButton, TokenUsageIndicator).
• Updated imports across chat/agents/knowledge pages to reference @/components/common/* instead of @/components/ui/*.
• Updated internal common components (e.g., markdownRenderer, filePreviewDrawer) to reference the relocated components.
