Use display name instead of user ID for plain text in mentions

[krille-chan]

Description

When creating a mention using @-completion, FluffyChat will currently put the Matrix User ID into the message body as the plain-text version of the mention, relying on clients to re-format the mention with a clickable badge with the display name. However, this doesn't work well with bridges that don't translate the mention ID to their local identifiers (e.g., IRC, Facebook). Here, other users will just see a nonsensical matrix ID in the text with no way to relate that back to the user being mentioned. It would be better to use the display name as the plain-text version of the mention, and only leave the user ID in the href of the mention link.

Additional information:

• OS and OS version: LineageOS 18.1
• Installed version of FluffyChat: 0.30.2
• (Android only) Which store are you using: Play store
• (Android only) Are Google Services available: Yes
