Pane(refactor): Replace deprecation warnings with DeprecatedError

why: Enforce immediate migration from deprecated APIs.

what:
- select_pane() raises DeprecatedError, use select() instead
- split_window() raises DeprecatedError, use split() instead
- resize_pane() raises DeprecatedError, use resize() instead
- get(), __getitem__() raise DeprecatedError, use attribute access
- set_width()/set_height() updated to use resize() internally
