fix: correct env var add form action path

The 'Add' environment variable form in app_detail.html was posting to
/apps/{id}/env, but the route is registered as /apps/{id}/env-vars.
This path mismatch caused a 404 when trying to add environment variables
from the app detail page.

Fix the form action to use the correct /apps/{id}/env-vars path,
matching the route defined in routes.go.

closes #156
