Add MetaData table

[vientang]

For convenience, let's have another table for tracking meta data that would be helpful for internal operations.

For example:

• lastGameRecorded: to prevent over fetching
• totalGamesPlayed: stat for admin dashboard?
• organizers: about us page?
• totalMembers: stat for admin dashboard?

Should evaluate the cost of adding, reading and writing to another table. Might be better not to do this considering our budget.

Closing this. If there's a need, we can reopen or create a new ticket.
