fix: convert hex AccountId to SS58 in referral/KYC queries

toJSON() returns hex format for AccountId fields but comparison was
against SS58 addresses, causing referrer matching to always fail.
- citizenship-workflow: encodeAddress for referrer in getPendingApprovals
- citizenship-workflow: handle both PascalCase and camelCase KycStatus
- referral: encodeAddress for referrer in getMyReferrals and getReferralInfo
