forge-oracle — add test verifying set_max_price_deviation() correctly blocks submissions exceeding the threshold

[Austinaminu2]

Summary

set_max_price_deviation() is implemented and submit_price() uses it, but there is no test verifying the end-to-end flow: set a deviation threshold, submit an initial price, then verify a large price change is blocked and a small one is accepted.

Tasks

• Submit initial price of 10_000_000 (1.0 USDC)
• Call set_max_price_deviation(1000) (10% max deviation = 1000 bps)
• Attempt submit_price with 11_100_000 (11.1% increase) — assert PriceDeviationTooHigh
• Attempt submit_price with 10_900_000 (9% increase) — assert success
• Attempt submit_price with 9_000_000 (17% decrease from 10.9M) — assert PriceDeviationTooHigh
• Call set_max_price_deviation(0) to disable — verify previously blocked price now succeeds
