fix: move hidden input off-screen and fix branch loading

- Move terminal hidden input to off-screen position (-9999px) to prevent
  text selection/caret visibility on mobile
- Add user-select: none to prevent any selection UI
- Fix create-session-form to use new listRepositoryBranches API signature
  (projectId, repoId) and access response.branches/default_branch
