What version of FlowSynx?

1.2.1

Describe the bug

The ITransactionService interface and its implementation TransactionService are no longer used and should be removed to clean up the codebase.

Affected files:

• FlowSynx.Domain/ITransactionService.cs
• FlowSynx.Persistence.Postgres/Services/TransactionService.cs

Proposed change:

• Delete both files.
• Remove any references, using statements, or dependency injections related to ITransactionService or TransactionService.
