Remove FSM integration to blockchain controller

[galt-tr]

This pull request removes all Finite State Machine (FSM) monitoring and reconciliation features from the operator. This includes the removal of the FSM configuration from the BlockchainSpec, all related controller logic, and the supporting code and dependencies. The changes simplify the codebase and reduce external dependencies.

Removal of FSM features:

• Removed the FiniteStateMachineSettings struct and the finiteStateMachine field from the BlockchainSpec in blockchain_types.go, eliminating FSM configuration from the CRD.
• Deleted the entire blockchain_fsm.go file, which contained all FSM-related logic, including state reconciliation and error handling.
• Removed FSM monitoring and reconciliation logic from the BlockchainReconciler in blockchain_controller.go, including the GetFSMState, ReconcileState, and error handling code.

Dependency cleanup:

• Removed the teranode dependency and all related indirect dependencies from go.mod, including those for FSM operation and gRPC communication. [1] [2] [3] [4]

Controller code simplification:

• Removed unused imports and the BlockchainClient field from the BlockchainReconciler struct in blockchain_controller.go. [1] [2]
