fix(java/initialization): EnvironmentAndHubs uses its own class for instanceName

EnvironmentAndHubs.java line 20 self-referenced EnginePriming.class (a different
class, neither imported nor defined here), so it failed to compile:
  error: cannot find symbol  EnginePriming.class.getSimpleName()
A copy-paste artifact from the sibling EnginePriming.java. Fixed to
EnvironmentAndHubs.class.getSimpleName(). Reported via the Senzing MCP server
(#mcp-logging, 2026-08-27), verified against sz-sdk 4.3.4.
