- persist eip712 payload by adding eip712PayloadReceived to updateVaultCipher
  trigger list, preventing a hung request after a service-worker restart
- wrap handleSign key reconstruction + signing in try/catch, sending
  signTypedDataError on failure instead of leaving the dapp promise hanging
- guard the eip712 payload JSON.parse and send signTypedDataError on
  malformed data instead of throwing during render
- advertise signTypedData in CasperWalletSupports and getActiveAccountSupports
  (software accounts only) so dapps can feature-detect EIP-712
- reject watch-only accounts (no secret key) before signing
- harden optional chaining when reading the signing account balance
- import FormatDistanceToken from the date-fns package root

* chore: update casper-wallet-core dependency to latest commit

* test(e2e): update failed transfer error heading for casper-js-sdk 5.0.12

The SDK bump 5.0.10 -> 5.0.12 changed the HTTP error format: a 500
response now throws HttpError(status, Error(statusText)), so the
transfer error screen renders 'Internal Server Error' instead of
'failed to send http request, details: Code: 500, err: Internal Server Error'.
