Fix jiti alias resolution in dev mode with tsx

When running from source with tsx, the jiti aliases pointed to .js files
that don't exist (only .ts files exist). This caused jiti to fall back to
different module resolution, loading a separate instance of theme.ts where
initTheme() was never called, resulting in undefined theme.

Now checks if .js exists and falls back to .ts for dev mode compatibility.
