fix(abstract-eth): add consolidate type and validation for TSS wallets

- Add 'consolidate' to allowed transaction types in verifyTssTransaction
- Implement consolidationToBaseAddress validation to ensure consolidation
  transactions send funds to the wallet's base address
- Fixes TSS wallet consolidation which was failing with "missing txParams"
