FINERACT-2050: Fix client transfer loan status transitioning to ACTIVE

[airajena]

Description

This PR fixes an issue where loans attached to a client remain in TRANSFER_IN_PROGRESS status after the client is successfully transferred to a new branch and the transfer is accepted. Since the loan was active in the previous branch, it should return to ACTIVE status in the new branch.

Changes

• Updated DefaultLoanLifecycleStateMachine to allow transitions from TRANSFER_IN_PROGRESS to ACTIVE (for normal loans) and OVERPAID (for overpaid loans).
• These transitions are triggered by LOAN_REPAYMENT_OR_WAIVER or LOAN_OVERPAYMENT events, which occur during the client transfer acceptance process.
• Added comprehensive unit tests in DefaultLoanLifecycleStateMachineTest to verify that TRANSFER_IN_PROGRESS correctly transitions to ACTIVE or OVERPAID.

Testing

• Added unit tests: testTransitionShouldWorkProperlyForLoanRepaymentOrWaiverWhenTransferInProgress and testTransitionShouldWorkProperlyForLoanOverpaymentWhenTransferInProgress.
• Validated that existing tests pass.
• Verified code quality with ./gradlew spotlessApply spotbugsMain spotbugsTest checkstyleMain checkstyleTest.
