build(deps): migrate the TipTap stack to 3.30.4

 ### Security
+- Patched an editor dependency vulnerability while preserving the existing formatting, collaboration-presence, safe-link, and exact document-restore behavior.
 - Raised workspace-wide transitive development-tool overrides for `fast-uri`, `nanoid`, and `postcss` to patched minimums, keeping the lockfile audit clean without changing runtime package authority.
 - Normalized isolated package-verifier temporary roots before containment checks on macOS.
