enhance(frontend): CWの注釈テキストが入力されていない場合はPostボタンを非アクティブに (#15639)

* add condition to disable post button when CW text is empty

* standardize condition by using 1<= inserted of 0<

* unify CW text length condition to improve readability

* add missing CW state check

* fix state check, add empty/null check, improve max length validation

* simplify CW validation by removing minimum length check

* Update CHANGELOG

* remove CW text validation in post()
