Rooms set to "Mentions and Keywords" still show badges for all messages

[andrewmurphyio]

Describe the bug

Rooms with notification mode set to "Mentions and Keywords" incorrectly show unread badges and counts for all messages, not just highlights (mentions).

This is similar to #375 / #2582 (muted rooms showing badges), but affects the MentionsAndKeywords notification type.

Reproduction

1. Set a room to "Mentions and Keywords" notification mode
2. Receive regular messages (not mentions) in that room
3. Observe that the room shows an unread badge with the total message count

Expected behavior

• Badge should only appear when there are actual highlights (mentions/keywords)
• Count should show highlight count, not total unread count

Root cause

In src/app/utils/room.ts, the getUnreadInfos() function only filters out Mute rooms:

if (getNotificationType(mx, room.roomId) === NotificationType.Mute) return unread;

For MentionsAndKeywords rooms, it still returns the full total count via getUnreadInfo() instead of filtering to show only highlights.

Platform and versions

• Cinny version: dev (latest)
• Browser: All
• OS: All

Often I use mentions and keywords for larger rooms that I still want to be updated on, but I don't want to be flooded with messages. I think this could be an intended feature
