fix(deps): remove the usage of methods from the gogo/protobuf

[Svarrogh1337]

fixes #1008
need to merge projectcapsule/capsule#1898 first.
Code and import path changes:

• Refactored import paths in main.go to use the new pkg/runtime/indexers and pkg/runtime/indexers/tenant locations.

Authorization middleware improvement:

• Change the logic in MutateAuthorization by directly assigning ResourceRules to the Status field instead of using the XXX_Merge method.
