Revert Typst SyncTeX attempt; clean up diagnostic logging

Typst has no --synctex CLI option (open feature request #289 since 2023).
Revert the frontend guard back to LaTeX-only and remove --synctex from
the Typst compile command. Also remove the temporary logger.warn calls
added for diagnosing the LaTeX synctex issue (now resolved).

The official Typst binary installation in Dockerfile-base is kept as it
is cleaner than using Quarto's modified fork for .typ compilation.
