chore(tui): fix eslint/prettier nits from npm run fix

- drop inline `import()` type annotation in useSessionLifecycle (import
  `PanelSection` at the top like everything else)
- include `panel` and `session.resumeById` in the useMainApp useMemo
  deps now that the event handler depends on them
- wrap the derived `selected` range in a useMemo so it has stable
  identity and stops invalidating the TextInput `rendered` memo every
  render
- prettier re-sorting of a couple of export/import lines
