add MAGMA prices_sui_tokens list

[loopy811]

Description:

Hi! I added in prices list Sui of new token "Magma Finance" - Paprika, Suiscan

[cursor]

PR Summary

Low Risk
Single static metadata row in a token allowlist; no logic or security-path changes.

Overview
Adds Magma Finance (MAGMA, CoinPaprika id magma-magma-finance) to the static Sui token registry in prices_sui_tokens.sql, including its full Move type address and 9 decimals.

That row will flow through the existing prices_tokens union so downstream price logic can resolve USD pricing for this coin like other listed Sui tokens.
