chore(cardano): enable tagged sets in tx serialization

[slowbackspace]

Description

This is the first of two PRs preparing Suite for the upcoming Cardano hard fork. Key updates include:

1. Transaction Serialization
   Post hard fork, all transactions must be serialized using tagged CBOR sets. This is already supported by Trezor/Connect (via tagCborSets param in trezorConnect.cardanoSignTransaction) and is now also supported by @fivebinaries/coinselection v3.

2. Staking Rewards Withdrawal
   Users withdrawing staking rewards will need to make a governance decision by selecting one of three options:

   • A vote of no confidence
   • Abstaining
   • Delegating to a DRep

Changes in this PR

• Upgraded cardano coinselection lib to support tagged cbor sets and voting certificate
• Utility functions for transforming vote delegation certificates (these will be used in the next PR introducing UI for governance):
  • updated prepareCertificates to convert from trezor-connect certificate format into coinselection lib format
  • introduced getVotingCertificates for creating voting cert in trezor connect format

Next Steps

The next PR will focus on introducing u UI to allow users to select their preferred governance participation option before proceeding with staking reward withdrawals.
