fix: make FrontendType mandatory in require_module_access

The require_module_access dependency was using path-based detection to
determine admin vs vendor authentication, which failed for API routes
(/api/v1/admin/*) because it only checked for /admin/*.

Changes:
- Make frontend_type parameter mandatory (was optional with fallback)
- Remove path-based detection logic from require_module_access
- Update all 33 module route files to pass explicit FrontendType:
  - 15 admin routes use FrontendType.ADMIN
  - 18 vendor routes use FrontendType.VENDOR

This ensures authentication method is explicitly declared at route
definition time, making it independent of URL structure and future-proof
for API version changes.
