Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=EF=B8=8F(frontend)=20optimize=20enter?=
 =?UTF-8?q?Room=20calls=20in=20useWaitingParticipants?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace sequential await inside the loop with Promise.all, since
each enterRoom call is independent.

This prevents unnecessary delays when multiple participants are
waiting (e.g. 10 participants previously resulted in ~10x longer
execution time).
