Force initialization before using the TXM

Description

Adds a started flag to the TransactionManager to prevent usage before initialization. The flag is set to true after the start() method completes successfully. Warning messages are added to key methods when they are called before initialization.

Internal new block events are now only emitted when the transaction manager has been properly started.
