Introduce a new CodeFilePreview component that wraps raw file text in a fenced code block, auto-detects language by extension, renders with Streamdown (plugins for code, math, mermaid, cjk) and shows line numbers. Import and use CodeFilePreview in FilePreviewModal for plain text/unknown/markdown fallbacks instead of raw <pre> blocks. Also adjust FilePreviewModal layout and styling for PDFs (use full height embed and conditional container classes) and tweak container overflow/padding behavior when previewing PDFs.
