Track storage

[jorgemanrubia]

This tracks storage at the account and board level.

Comments, cards, boards will notify up storage changes, offering an opportunity to store the change to the ancestors in the containment hierarchy.

We only count the storage taken by Action Text attachments for now.

Thanks for @packagethief for feedback on the approach, based on our experience with Basecamp 🙏

• [ ] Move board update to job too
• [ ] Run migration in production

Should we display "storage used" somewhere on the Account Settings page?

I was trying to get the internals here, but yeah that will be the next step once this gets merged (cc @jzimdars)
