Server(refactor): Replace deprecation warnings with DeprecatedError

why: Enforce immediate migration from deprecated APIs.

what:
- kill_server() raises DeprecatedError, use kill() instead
- get_by_id() raises DeprecatedError, use sessions.get() instead
- where() raises DeprecatedError, use sessions.filter() instead
- find_where() raises DeprecatedError, use sessions.get() instead
- list_sessions() raises DeprecatedError, use sessions property instead
- _sessions, _list_sessions(), _list_windows(), _update_windows(),
  _list_panes(), _update_panes(), children all raise DeprecatedError
