v1.6.7: add settings.system permission, move numbering/VAT to company tab, rename security tab to roles

- New settings.system permission with migration (idempotent INSERT)
- requireAnyPermission helper for route guards accepting multiple perms
- Move document numbering + currency/VAT cards from system tab to CompanySettings
- Rename security tab to roles, add canManageSystem alongside canManageCompany
- TOTP required endpoint and system-info now use settings.system
- Roles list now includes user_count
- Sidebar Settings link includes settings.system
