fix(webapp): show the real app version instead of v0.0.0 in organization settings

The Vite SSR bundle resolves workspace packages to TS source, where the
VERSION constant is the unstamped 0.0.0 placeholder; the stamping script
only patches dist output, which the bundle never reads. A small Vite
plugin now performs the same substitution on the source version modules
of core and trigger-sdk during bundling, so the settings page and the
version headers the webapp sends carry the real version again.
