Fix typing and pasting different behaviour in chat

### Description of the issue
When someone is using the chat and is typing HTML text, links are not created on the chat, but if someone copies a text with links, those links are created as links.
Platform is using @tiptap/extension-link and this library is having some issues when links are displayed like [https://github.com/ueberdosis/tiptap/issues/5290](https://github.com/ueberdosis/tiptap/issues/5290)

### Your environment
* Version of huly [a471415](https://github.com/hcengineering/platform/commit/a4714150ac8f9534d61654af907923f55860b590)
* Browser Chrome 126.0.6478.126
* Your operating system: Ubuntu 22

### Steps to reproduce
- Go to the chat.
- Type a HTML link text like 'https://curl2url.com' and this link is not displayed in the chat.
- Copy a link, and this link will be displayed in the chat.
- Type "FOO_BAR.MP3".

### Expected behaviour
- Links should be displayed in the chat in both ways or in any way, to match typing and pasting behaviour?
- Links should be displayed correctly

### Actual behaviour
- Typing HTML text link is not displayed correctly
- Some links are not displayed correctly

### Possible solutions
Stop using @tiptap/extension-link library and fix how links are displayed
