fix: room members count reactivity

[abhinavkrin]

Proposed changes

Fixes the discrepancy in group member counts between the Rocket.Chat mobile and desktop apps. The counters endpoint for channels, direct messages, and groups has been updated to exclude deactivated users, aligning the behavior across platforms.
This PR RocketChat/Rocket.Chat#36236 will fix the members count in the counters endpoint used in the app.

How to test or reproduce

1. Create a room with many users
2. View the members count in RoomActionView
3. Deactivate a user member without removing them from the room.
4. View again the members count in RoomActionView. It should not include the deactivated users in the count.

If the issue is the endpoint including deactivated users, why we should fix it with a reactivity refactor on client?
Shouldn't we fix the endpoint?

Yes, I have created another PR that fixes the issue. RocketChat/Rocket.Chat#36236
But we will need to update the mobile reactivity too. Currently and Initially, mobile app do get the values from the counters endpoints. But it has also subscribed to room changes and sets the members counts to back to the Room.usersCount (it should have been the value from the endpoint).

Also, this pr also fixes to show room members from counters for the DMs
