Fixes for the admin assistant and class editing.
- Asking the assistant to turn on a feature (for example "open online purchasing") is no longer treated as a request to open a page. The assistant previously said it was opening a page while nothing moved; it now answers the actual question. Genuine requests such as "Open the Passes page" or "Take me there" still navigate as before.
- The primary and additional instructor pickers in class editing now load correctly when the assistant fills in the form for you, instead of only after you open that section yourself.
- The Traditional Chinese label for the substitute setting now makes clear that it marks the instructor as a substitute, rather than granting a permission.
