feat(cli): improve attestation push result in table format

[jiparis]

This PR improves the way att push result is shown. It uses now the status action logic (in full mode) before running the actual push to gather all the information from the current attestation.

✗ go run app/cli/main.go --insecure --token $TOKEN att push --key ./cosign.key
WRN API contacted in insecure mode
