fix(client): 账号菜单改 showMenu 等宽触发器 + 向上弹（修菜单溢出盖内容）

上一版用 PopupMenuButton width:218 + offset:-12 反而把菜单外扩、右缘越过侧栏盖住内容区。改为 GestureDetector + showMenu，菜单宽度 = 用户区实测宽度（自动与侧栏内容等宽、绝不溢出），底部空间不足 showMenu 自动向上弹、不遮触发器。加 user_menu_width_test：点开后断言菜单宽≈194、右缘≤218（弹出态回归）。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TSKEiHsvauyxYUW2itzUXX
