PR Summary

Low Risk
Single static catalog row with no logic or pipeline changes; wrong mint/decimals would only affect SLX pricing accuracy.

Overview
Adds Solstice (SLX) to the static Solana token catalog in prices_solana_tokens.sql, using CoinPaprika id slx-solstice, mint SLXdx4BUt2v9uJQNzWqSfzTJ9UKLUDsvxHFMEEdrfgq, and 6 decimals—inserted alongside existing Solstice-related entries (e.g. eUSX) before the tokenized equities block.

That row feeds the prices_solana.tokens dbt model and downstream prices_tokens union so SLX can be priced like other listed Solana SPL tokens.
