Move ASCII banner into boot sequence, fix remaining UI issues

- Remove collapsible ASCII banner from dashboard (was cluttering the UI)
- Show ASCII banner in the boot overlay on first session visit, above
  the boot messages, with a 400ms pause before messages begin
- Add scroll fade indicator (green-tinted gradient edges) to .table-wrapper
  so users can see when the table is horizontally scrollable
- Fix null guards for tab switcher in ticket.js (tabEl, activeBtn)
- Fix Reset → RESET uppercase in AuditLogView and UserActivityView
