Per-miner RSR

[bajtos]

We have been asked to provide per-miner RSR stats in addition to the current "all miners leaderboard" dataset.

What we want

A new spark-stats API

• Accept a miner ID (e.g. f0814049) and an optional date range (e.g. ?from=2024-11-01&to=2024-11-30).
• The response should list RSR for each day in the date range for the selected miner only. RSR means the following fields: total, successful, success_rate - see the output of https://stats.filspark.com/retrieval-success-rate for an example.
• Re-use the helpers & building blocks we already have in place in spark-stats.
• Remember to update README to document the new endpoint

Stretch goal

A new Observable dashboard showing per-miner stats. At the top, the dashboard should provide a text field for entering the miner ID. Then, there should be a chart showing how this miner's RSR evolved over time. (We will be adding more charts incrementally over time.)

Prior art:

• https://dashboard.filspark.com
• https://github.com/filecoin-station/spark-dashboard

Workaround: implement a "scraper" that iterates over multiple days, downloads the "all miners" data for each day, and builds the database that way.

Shipped to the dashboard. Great work
