fix(share): terminal access for late joiners, auto-scroll, inventory scroll

- A guest who joined after the host enabled the terminal stayed read-only; the
  host now re-sends the terminal state on join (req_full), so the terminal works.
- The shared terminal follows the cursor to the bottom as output arrives (ls -la)
  instead of staying scrolled up.
- The Inventory page preserves scroll position on refresh (and skips re-rendering
  unchanged data), so it no longer jumps to the top while you're reading.
