chore(helm): address @0x666c6f review on CODEOWNERS and image versions

- CODEOWNERS: add @0x666c6f as a mandatory codeowner alongside the
  teams, on every pattern (incl. /helm/) so he is a required reviewer
  repo-wide, not only for files matching the default `*` rule.
- values.yaml: bump erpc and erpc-validator image tags 0.0.77 -> 0.1.3
  to match the latest prd values in morpho-org/morpho-infra-helm.
