fix(hardware-trezor): support derivationType in getXpub method

- add `derivationType?: MasterKeyGeneration` to `GetTrezorXpubProps`
- update `getXpub` and `createWithDevice` to accept and pass `derivationType`
- include `derivationType` in `cardanoGetPublicKey` call
- add mapping from `MasterKeyGeneration` to Trezor `CardanoDerivationType`
- improve seed length handling for ICARUS vs ICARUS_TREZOR
- import `MasterKeyGeneration` type from `@cardano-sdk/key-management`
- test all derivation types (ICARUS, ICARUS_TREZOR, LEDGER)
- verify parameter passing from `trezorConfig` to `getXpub`
- cover error handling (TransportError, AuthenticationError)
- add integration tests for `createWithDevice`
- mock Trezor connection to avoid device dependencies
- improve test organization with shared utilities and hoisted setup
- enhance coverage for master key generation schemes
