G2-Pair1: VMS module — final submission

[WhoamiI00]

Visitor Management System frontend (final submission for IT3C03). Roll numbers: 23BCS028, 23BCS208, 23BCS017

New module at src/Modules/VMS/:

• VmsStaffPage — gate operations: register, issue QR pass (one-click verify+issue chain), verify, record entry/exit, deny, log incident, assign/release escort
• VmsAdminPage — blacklist mgmt (by id_number or visit_id), Grant VIP Status, Generate Reports + PDF, Import Visitor Data (with sample loader), Export Visitor History, System Configuration, Configure Visiting Hours, Configure Access Zones
• VmsAccessGuard — route-level RBAC gate; calls /vms/me/, redirects users without HostAuthority to /dashboard, blocks non-admin users from the admin console
• useVmsController — shared state hook
• VmsTable — Visitor Records / Security Snapshot / Recently Registered
• api.js — axios wrappers for every /vms/ endpoint
• helpers.js — option lists, default payloads (Aadhaar default)
• vmsExportPdf — client-side PDF generators for reports + history

Minimal wiring deltas (only VMS-specific lines):

• src/App.jsx — 2 imports (VmsPage, VmsAccessGuard) + 3 Route blocks for /vms, /vms-demo-staff, /vms-demo-admin
• src/components/sidebarContent.jsx — VmsIcon import, /vms/me/ fetch to resolve user's HostAuthority level, sidebar entry, conditional filter so the entry only renders for users with VMS access

No other modules touched.
