Improve performance of Charts on 1+ years of data

[devinmatte]

When fetching charts over years (for example data from 2022-2026), we are fetching 100% of days.

This means that we're fetching a huge amount of data, and in many cases timing out. We should improve the performance so these charts load properly.

Some ideas of how we can do that:

• Batch responses into weeklong data points instead of daily
• Chunk responses for partial loading / splitting request into multiple requests less likely to time out
• Add cache layer to improve second load attempt after timeout
