Previously, some functions that conceptually belong to the connection needed to be in the Controller, since we didn't have a place to put them.
This fixes that by extending the Connection class in a similar way as we extend the Room class.
- Update the message event and user models so that the full source url is output.
- Separate the reply author into its own role
- Create an empty user object that can be passed so that the QML code no longer needs to check if certain parameters exist.
- Make avatarForMember return and empty QUrl if a valid avatar cannot be found and make use in the user and event models
As well as cleaning up the QML this should also stop the QML Image: Media id '' doesn't follow server/mediaId pattern spam in the log.
Also modernize the codebase where possible (e.g use required properties,
reorder properties, fix warnings, don't use Action when not needed)

This MR goes over text and cleans it up to be more unifying. Mostly just lowercasing words in non-titles, but it also changes the "show fancy effects" text to be clearer with its meaning.
It also fixes the room access being printed in the room settings: 
I'd like to do a second pass later with another MR to unify triple dots (...) and ellipsis (…)
Add the option to set powerlevel to userdetaildialog.
This is done by making the powerleveldialog into it's own file and using that.

Fix Crtl + F not working by only having the shortcut assigned to a single searchfield.
- Ctrl + F is now for the roomlist search
- The user search in the room drawer is now ctrl + shift + f
- for the emoji picker and qucik switcher these have the shortcut removed and focus is managed by the popup.
BUG: 462524
This converts the emoji dialog in the chatbar to be the same popup as for reactions. This includes:
- EmojiPicker and ReactionPicker were already similar and are made identical, as such ReactionPicker no longer needed
- Emoji dialog used for both reactions and chatbar emojis
- Add some parameters to allow for different use cases (include custom emojis and whether selection closes the popup)
