Subject: [PATCH] fix(service-party-app): remove password input from Sign page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current system uses empty password for share encryption, so the password
input field is unnecessary. Removed from both Transfer and Sign pages.
