pricing: phase-1: add data usage / Accessible for Rill Projects

[royendo]

• Expose dataSizeBytes in the runtime GetInstance API response

• Show a visual fill-pill on the project status overview for Rill-managed OLAP projects

• Team plans: bar fills proportionally toward 10 GB cap; deepens to primary-700 at capacity

• Pill links to the tables detail page

Data usage + Slots — only for Rill-managed OLAP (gated by !olapConnector || olapConnector.provision):

[royendo]

@ericokuma for functionality, (not exactly pricing, but good to add while we're here)
for users to see how much data the project is using as a whole (if you've got a lot of models, hard to see full usage) requested a few times from customers.

In the case of self-managed, it is Data accessible, else its Data usage. clicking takes you to the Tables tab for detailed view.
