Muting reactions per user

### Your use case

#### What would you like to do?
Mute reactions

#### Why would you like to do it?
Someone starts spamming reactions, leaving you without a option to do something about it except leave the call

#### How would you like to achieve it?
Right clicking on someone allow for a "mute reactions for me" toggle

### Have you considered any alternatives?

Trying the option "Mute for me" toggle, but that only mutes voice.

### Additional context

_No response_

Start by tracing the existing “Mute for me” toggle and the call reaction handling in the TypeScript frontend. Confirm how a user-specific mute setting would affect incoming reactions, then verify that right-clicking a participant exposes the requested toggle and that muted reactions no longer appear for that user.
