fix(ui5-tokenizer): allow copy/cut of focused token when not selected

When a token is focused but not selected, Ctrl+C now copies its value
to the clipboard. In readonly mode, Ctrl+X copies without deleting.
Also removed redundant selected filter in _fillClipboard since callers
already pass the correct token list.

Fixes #13446
