refactor(astrolabe): replace client-side PDF.js with server-side PyMuPDF rendering

Replace the client-side PDF.js viewer with server-side rendering using PyMuPDF.
This avoids CSP worker restrictions and ES private field access issues that
affected Chromium browsers.

Changes:
- Add /api/v1/pdf-preview endpoint to MCP server (management.py)
- Add pdf-preview route and controller action in Astrolabe PHP backend
- Refactor PDFViewer.vue to display server-rendered PNG images
- Remove pdfjs-dist dependency and client-side PDF loading code
- Use @nextcloud/axios for CSRF token handling in PDFViewer

The server downloads the PDF via WebDAV, renders the requested page with
PyMuPDF at the specified scale, and returns a base64-encoded PNG image.
