chore: Minor update to adjust naming and clean up wrapping

[jsync-swirlds]

Reviewer Notes

This PR is a vehicle for clearer discussion of some recommended changes that we were struggling to discuss in a previous PR.

• Renamed sessions to remove redundant "Verification" and "Block" terms.
• Renamed session factory to include criteria in the class name instead of redundant words
• Added some message variables and cleaned up excessive wrapping
• Removed exception-as-goto usage in VerificationServicePlugin; replaced with if/else usage.
• Moved failure notification to a new method for consistency.
• Applied spotless which further adjusted wrapping

Looks good, I like the shorter and improved naming. 👍
