chore: update dependencies and improve MermaidBlock security

- Updated mermaid from version 11.13.0 to 9.1.7 for compatibility.
- Upgraded next from version 14.2.21 to ^14.2.35 for the latest features and fixes.
- Added @types/dompurify and isomorphic-dompurify for improved sanitization.
- Replaced innerHTML assignment in MermaidBlock with sanitized SVG using DOMPurify.
- Updated eslint-config-next to ^16.2.4 for better linting support.
