Add test for PDA Stake Account derivation

This test verifies the correct derivation of multiple PDA addresses using various inputs like miner, programId, staker, and oreSolMeteoraLpTokenMint. It logs the derived addresses and also deserializes the delegatedBoostAddress to ensure correct account information retrieval.
