chore(admin): rebrand visible CRMEB references to syj.fsgx.cn

Strip CRMEB/crmeb from user-visible copy on auth, kefu, supplier login,
setting guides, storage docs, mobile page mocks, and system maintain
file editor. Replace external crmeb.com URLs with syj.fsgx.cn (sms
console iframe and license-protected file headers/comments left
untouched). Default brand_name on wechat membership card switches to
"芍药居".
