feat(examples): Implement sponsors (p+r) for sponsor service management

[linhpn99]

From Proposal #2152 :

• This PR proposes a new realm specifically for managing information related to sponsor services. This information will be readily accessible to dApps (decentralized applications) within the ecosystem
• Please note that the realm's functionalities are currently limited for demonstration purposes. We are actively working on further development and will introduce additional features in the future
