The Mobile namespace only contained an API auth controller (Sanctum token
login/logout/check) that is not mobile-specific. Relocated to
Company/Auth/AuthController alongside the other auth controllers.
V1/Admin -> Company (company-scoped controllers)
V1/SuperAdmin -> Admin (platform-wide admin controllers)
V1/Customer -> CustomerPortal (customer-facing portal)
V1/Installation -> Setup (installation wizard)
V1/PDF -> Pdf (consistent casing)
V1/Modules -> Modules (drop V1 prefix)
V1/Webhook -> Webhook (drop V1 prefix)
The V1 prefix served no purpose - API versioning is in the route prefix
(/api/v1/), not the controller namespace. "Admin" was misleading for
company-scoped controllers. "SuperAdmin" is now simply "Admin" for
platform administration.
