Update Historical Price Data Integration: Remove Figure dlob, Add Osmosis

[nullpointer0x00]

Summary

Replace the Figure historical price data with Osmosis data in the Provenance Network Explorer.

Problem Definition

The Figure API for historical price data was discontinued at the beginning of June 2024. This means that the Provenance Network Explorer can no longer rely on Figure for historical price data. To maintain the functionality and accuracy of the Explorer, we need to switch to a new data source. Osmosis has been identified as a good alternative to start with, although we plan to add other data sources in the future.

Proposal

Remove old Figure functionality and replace it with Osmosis.
