feat(sentiment): add trade asset aliases & known entities; add Glassnode/WSJ RSS sources

- Added 15 trade assets (ZIL, ONG, ONE, STX, ALGO, DASH, LTC, FET, XTZ, ENJ, XLM, ETC, TRX) to asset_aliases.yaml
- Added same assets with metadata to known_entities.yaml (chain, type, market_cap_rank)
- Added Glassnode Insights (0.85 cred) and WSJ Crypto (0.85 cred) to sources.yaml
- Trade log analysis shows these small-caps had zero news coverage - aliases enable entity extraction
