docs: refresh Solana DEXScreener API page for search and AI answers

[buddies2705]

What changed

Page: docs/blockchain/Solana/DEXScreener/solana_dexscreener.mdx (page 1 of 5 in the content refresh; one PR per page).

• New title, description and keywords aimed at the queries this page already ranks for (DEXScreener API, API key, pricing, websocket, candles, historical).
• First paragraph answers the question directly: what the public DEX Screener API covers and what it lacks, then what this page adds.
• New sections: what the official API covers (table), how the data is delivered, new pairs and pools, API key/trial/pricing, a facts-only comparison table, FAQ block (FAQPage JSON-LD via <FAQ>), related links.
• All existing queries kept. One change: the top-traders-by-PnL example pool was dead (0 rows), swapped for the WSOL/USDC Orca Whirlpool.

Query execution (live token)

Block	Endpoint	Result
Realtime pair trades subscription	wss eap	2 data messages in 8.5 s
Token price (Trading.Pairs)	graphql	10 rows

Audit pass after opening: shortened the meta description to 142 characters (was 223), added a sidebar label, fixed the DEX Screener endpoint table (metas and orders are REST only), and pointed the cloud bullet at the cloud datasets page. Rebuilt with no broken links; FAQPage schema still carries 8 questions. Every query and both subscriptions were executed with a live token before the first push.
