Security review caught: per-row hover actions (users.js) and async
user picker (shop.js, gam.js) interpolated user-controlled name into
JS string literals inside onclick. LS.esc() escapes & < > " but
NOT backslash; the .replace(/'/g, '\'') fallback was broken.
Attack: any authenticated user could set their name to
a\'); alert(1); //
via PATCH /api/auth/profile (stripTags doesn't strip \) — admin
viewing the users/shop/gam picker would execute arbitrary JS.
Fix: switch from JS-string interpolation to data-uid/data-name
attributes, read via dataset in handler. esc() correctly escapes
for HTML-attribute context; dataset returns the raw string with
zero parse re-entry.
