fix(set-password-copy): [Auth/PM-25119] Update copy for flows where the user is setting and initial password (#16169)

Updates the copy on flows where the user is setting an initial password. Instead of saying "New master password" and "Confirm new master password", it should say "Master password" and "Confirm master password" for these flows.
