MaxBuyPrice-Skala korrigiert + Blockchain-Abo-Logik extrahiert & getestet

Browse Source 
- Fix (Richard): MaxBuyPrice-Skalen-Korrektur analog PreRedeemLimit
  (Migration FixMaxBuyPriceScale: Werte > 1 wie 98.0/99.0 -> /100 = 0.98/0.99;
  auf MySQL angewendet). Cap greift bei den betroffenen Accounts jetzt wieder.
  Beschreibung des Feldes um den Skalen-Hinweis ergaenzt.

- Testnetz erweitert: reine Klasse BlockchainSubscription (Logic/) fuer das
  Alchemy-Abo (PadAddress + Filter-Batching in 3er-Chunks, Buy=Topic3/Sell=Topic2
  je Chunk). AlchemyWebsocketService ruft sie jetzt (verhaltensneutral;
  Konstanten + lokale Methoden entfernt). BlockchainSubscriptionTests: 13 Faelle
  (Padding, Chunk-Anzahl 0/1/3/4/6/7, Topic-Zuordnung, CTF-Adresse/Topics).

Gesamt 137 Tests gruen. Build/Smoke gruen.
