Subject: [PATCH] fix: read stored project compiler for quartoFlavor update

options.compiler is set from req.body.compiler which the frontend never
sends, so the condition was never true and quartoFlavor was never written.
Use ProjectGetter to read the stored compiler instead. Fire-and-forget so
it does not delay the compile response.
