examples/credential_management.sh and .ps1 both invoke contract methods (set_credential_policy, check_credential_rotation, rotate_credential) that don't exist anywhere in the contract

[Haroldwonder]

Both examples/credential_management.sh and examples/credential_management.ps1 repeatedly invoke set_credential_policy (lines 87, 99 in .sh; 88, 96 in .ps1), check_credential_rotation (line 158 in .sh; 142 in .ps1), and rotate_credential (line 196 in .sh; 164 in .ps1) as contract entry points via the CLI invoke pattern. None of these three names exist anywhere in src/contract.rs or anywhere else in src/ (verified via repo-wide grep) — running either script end-to-end fails at "Setting policy for KYC provider" with an unknown-method error from the underlying soroban contract invoke/CLI call.
