Grant proposing rights to new charter members (#10166)

closes: #10133
refs: #10133

## Description
The PR builds on #10164, introducing code changes to initiate a new charter committee instance and send invitations to the members.

### Security Considerations
The EC Charter is important for deciding who can suggest changes to governed contract parameters. If the wrong people are given access or if expired members aren't removed, it can lead to security risks by letting unauthorized individuals propose changes. 

Since we're starting a new contract, old charter members can still propose questions, even though they can't vote. This still creates a potential security issue, as people who are no longer active can still influence the process. These people might fill the system with too many unnecessary or harmful proposals, which can make it difficult to focus on the important ones and slow down the decision-making process.
