Rewires module installation to use slug + version + checksum_sha256 instead of the opaque module identifier. ModuleInstaller splits marketplace token handling out of install() into helpers, adopts structured error responses, and validates the downloaded archive's SHA-256 against the marketplace manifest before unpacking.
ModuleResource is simplified to accept an already-loaded installed-module instance rather than fetching it from state, exposes access_tier and checksum fields, and drops the auto-disable-on-unpurchased side effect that was bleeding write logic into a read resource. UnzipUpdateRequest accepts a nullable module with a conditional module_name field so the same endpoint serves both app and module updates.
ModulesPolicy::manageModules now short-circuits for super-admins so administration flows (token validation, store state) are not blocked on a company-scoped ability. Two new feature tests cover both the authorization bypass and ModuleResource serialization.
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.
