feat: move logout button from About tab to Connection tab (#487)

- Remove the Logout button from the About tab content.
- Add the Logout button at the bottom of the Connection tab so users
  can sign out directly where they manage their connection.
- Delete the unused, duplicate AboutSection() composable (it was never
  called and carried its own Logout button) to keep a single source of
  truth for the action.

Logout behavior is unchanged: it still calls viewModel.logout() then
onLogout() (navigates to login). Verified with assembleDebug + ktlint.
