Atrum: correct inspired_by to RFP-08

[TechnicallyKiller]

One field on one entry. 109 entries in, 109 out, and only the Atrum row differs.

inspired_by: RFP-07 → RFP-08.

My original registration said RFP-07. I corrected it to RFP-08 before the bot picked it up, but the amend landed after the PR had already been applied and closed, so the correction never made it in.

RFP-08 is the accurate one. Atrum is a sealed-bid batch auction — orders are unreadable until the batch closes, and every trade in a batch settles at one uniform clearing price. The prediction-market framing in RFP-07 is the application; the mechanism is the auction, and the mechanism is what is actually novel here. The two teams already under RFP-07 are pooled markets with no early exit, which is a different product.

The one_liner is also updated to lead with the mechanism rather than the category.

No other entry touched.

This changes rows that are already in the table (atrummarkets/atrum-starknet), and I cannot tell that they are yours - you are not listed in their team on main, and you do not own the repositories they point at. Leaving this for a maintainer. If it is your project, say so here.
