fix: upgrade error-prone to 2.49.0 and fix new compilation warnings

[vorburger]

This PR upgrades error-prone to version 2.49.0 and resolves the new compilation warnings introduced by the update. Specifically:

• Fixed AssertThrowsMinimizer warning in CircularFifoQueueTest.java by extracting iterator creation outside of the assertThrows block.
• Fixed AssertThrowsBlockToExpression warning in ManagedProcessTest.java by replacing the block lambda with an expression lambda within assertThrows.
