fix: adjust pool retirement epoch to work with fresh devkit chains

Change the hardcoded retirement epoch from 19 to 2 to fix validation
errors on fresh devkit/testnet environments where current epoch is 0.

The Cardano protocol requires:
  current_epoch < retirement_epoch <= current_epoch + eMax (18)

With epoch 0, retirement epoch 19 exceeds the maximum allowed offset,
causing StakePoolRetirementWrongEpochPOOL validation errors.

Using epoch 2 provides a conservative offset that works on fresh chains
while still allowing successful pool retirement testing.

Changes:
- Update pool retirement epoch from 19 to 2 in PoolTransactions.java
- Update devkit genesis configuration and test data

Related error:
  StakePoolRetirementWrongEpochPOOL
  (Mismatch {mismatchSupplied = EpochNo 19, mismatchExpected = EpochNo 0})
