fix: preserve scroll position after editing forward rules (#319)

* fix(dialog): prevent both open and close auto focus to avoid page scroll

Add onOpenAutoFocus handler to prevent Radix Dialog from auto-focusing
content on open, which can cause unwanted scroll behavior.

* fix(dialog): remove onOpenAutoFocus, keep only onCloseAutoFocus

Remove onOpenAutoFocus handler that was causing scroll issues on first open.
Keep onCloseAutoFocus to prevent scroll to trigger element on close.

Key fix: Move {...props} before onCloseAutoFocus to prevent override.

* fix(dialog): prevent scroll to top on modal close

- Move {...props} before onCloseAutoFocus to prevent override
- Simplify handler to just e.preventDefault()
- Apply fix to both dialog.tsx and modal.tsx

* fix: preserve scroll position after editing forward rules

Move getForwardDisplayFlow outside component to prevent unnecessary
re-renders that reset scroll position on save.
