feat: add button required for rpc reproduction
Instructions:
- Two participants A and B in the same room
- A is configured to send a rpc on `test`, B is configured to listen to rpc on `test`
- Enable NLC "very bad network" mode
- Click "flood reliable data" on A, and send the rpc on A
- Rpc from A -> B will get a connection timeout
- On B, change network to "Offline"
- `currentRoom.remoteParticipants.values().next().value.connectionQuality` on A should go to "poor" within ~20s or so, eventually will get to lost
- On B, change network back to "no throttling"
- B will do a reconnect and the RPC will never be received
