Empty state persistence in new conversation modal

Business problem

In the 'Start conversation' menu, previously entered text or contact details (such as phone numbers and email addresses) persist even after being manually deleted by an agent. This cache behavior causes confusion and increases the risk of data privacy issues, as it is easy to accidentally send a message to the wrong recipient if the fields do not stay empty after being cleared.

Wished result

Content and contact information in the 'Start conversation' modal should be permanently removed once deleted. Reopening the menu should present clear fields instead of restoring previously discarded information.
