Rename controller namespaces: drop V1 prefix, clarify roles

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.
