TaxBaik CI/CD / build-and-deploy (push) Successful in 2m42s
feature: implement persistent login username and remember-me checkbox
Problem: Login form showed remembered username from localStorage, but didn't
restore the 'remember me' checkbox state. Users had to re-check the box on
each login attempt, defeating the purpose of the remember feature.

Solution:
1. AdminLoginForm: Add isRememberChecked field and RememberedCheckboxKey constant
2. OnInitializedAsync: Restore both username AND checkbox state from localStorage
3. admin-session.js bindLoginForm: Restore checkbox.checked from localStorage
4. admin-session.js submit handler: Save checkbox state alongside username

Result: Complete round-trip persistence - when user checks 'remember me' and
logs in, both username and checkbox state persist until explicitly cleared.
