feat: polish items #26-29 — mobile CSS, error pages, rate limiting, session manager

#26 Mobile responsive:
- Hamburger button (SVG) in topbar for all three panels (admin/user/reseller)
- Sidebar overlay div for click-outside-to-close on mobile
- nova.js: DOMContentLoaded toggle handler with overlay and auto-close on nav click
- nova.css: sidebar-overlay, page-header, panel/panel-header, table, btn-success/warning/danger/secondary/xs,
  badge-muted; mobile media query shows toggle, fixes stats-grid/modal/panel-header layout

#27 Custom error pages:
- /errors/404.php and /errors/500.php with NovaCPX dark theme matching panel design
- Apache ErrorDocument 400/401/403/404/500/503 for ports 8880/8881/8882 with Alias /errors

#28 API rate limiting:
- api_rate_limits table (migration 004) with per-IP per-bucket counters
- api/index.php: 10 req/min for auth endpoint, 120 req/min for all others
- Returns X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset headers
- Returns 429 Too Many Requests when exceeded; rate limit failure is non-fatal

#29 Session Manager:
- sessions.php endpoint: list/revoke/revoke-user/revoke-all
- Admin panel Sessions page: table of active sessions with user, role, IP, browser, timestamps
- Revoke single session, revoke all for user, revoke all sessions (self-evicts)
