fix(webapp): show the real app version instead of v0.0.0 in organization settings (#4611)

## Summary

Since the move from the Remix compiler to Vite
([#4188](#4188)), the
"App version" on the organization settings page shows `v0.0.0` unless
the image was built from a semver release tag (which bakes in
`BUILD_APP_VERSION`). Self-hosted builds and any image built from `main`
are affected. This restores the real version.

## Root cause

The Vite SSR bundle resolves workspace packages to TS source via the
`@triggerdotdev/source` condition, so `@trigger.dev/core`'s `VERSION`
constant is bundled as its raw `"0.0.0"` placeholder.
`scripts/updateVersion.ts` still stamps the real version at build time,
but only into the packages' dist output, which the bundle no longer
reads. The old Remix compiler bundled the stamped dist, which is why
this used to work.

The fix is a small Vite plugin that applies the same substitution to the
source version modules of `@trigger.dev/core` and `@trigger.dev/sdk`
during bundling. Beyond the settings page, this also restores real
values in the `trigger-version` request header and the version
attributes the bundled packages emit.

Verified by building the server bundle and confirming the VERSION
constants carry the package versions, with no `"0.0.0"` occurrences left
in the build output.
