feat(members): add member ID to members list

This commit introduces a 'Member ID' column to the members table, making it the first column for easy reference.

- The member data schema and sample CSV have been updated to include the `memberId`.
- The members page now displays the `memberId` for each member.
- Additionally, a version query string has been added to the hero image URL to force a cache refresh.
