fix(observability): switch source map upload to glitchtip-cli

@sentry/vite-plugin uses sentry-cli which creates release entries but
doesn't upload files to GlitchTip's API correctly. Switch to the native
glitchtip-cli which uses the debug ID inject+upload approach that
GlitchTip actually supports.
