Fix login and panel visibility for user and reseller portals

- initUser/initReseller: show main-layout and hide auth-check on
  successful auth (was never shown, causing blank page after login)
- Fix login form IDs in user/index.php and reseller/index.php:
  changed l-user/l-pass/login-err to li-user/li-pass/li-err to
  match what doLogin() reads; add onsubmit handler so form works
  immediately without waiting for JS to replace it
- Wire logout button in both boot sequences
- Fix data.accounts → data in reseller.js (same paginate() bug as admin)
- Reset myron user password to Joker1974!!!
