Notifications triggered by keywords don't decorate messages - Highlight keywords in a pill

[nadonomy]

Should follow the same convention as @mention decoration— currently with the notifying word in a pill and the entire message highlighted red.

Doesn't look like it does anything really:
I configured a keyword and ask someone to mention it but I had no noisy notifs nor visual highlight.

In the Electron (macOS) build I got a system level notification— if you're in a browser it's worth investigating if the browser suppressed it?

The lack of any kind of highlighting on mentions/keywords, makes the client almost impossible to use with active channels. People endup thinking that you ignore them when in fact your fail to spot the messages.

I'm getting notifications (both on mobile and desktop) for keyword highlights, but when I open the client I have to (often painstakingly) search for the message because it isn't decorated. Mentions work fine.
