feat: add the ability to reply with any filetype

[nushea]

Description

Whenever I talk with people and they ask me to send them a file or i want to reply with an image to something they say I currently have to reply with an empty message and then the image/file.

This fix would allow anyone to reply with any file or a sticker to an event.

Also while you can send multiple files in one burst or a file and text, only the topmost item gets the reply event so it doesn't show as many reply icon visuals as there are events, with the reply working as before for text+file, with only the text having the reply tag as it is always the topmost item.

Additionally the older flow where you couldn't reply with images/files has confused all of the people that i have on-boarded or that were new to the platform

Example of how this feature could be used

Fixes #2659
(accidentally closed #2706 by renaming the branch to give my local branches proper names - without realizing it automatically closes them on github/cinny)
