feat(eip712): improve account presentation — show public key, fix hash label, adaptive row wrap (WALLET-1321)

[ost-ptk]

What & why

WALLET-1321 — improve how accounts are presented in EIP-712 signature requests.

After WALLET-1251 fixed address decoding, account rows display the bare 32-byte account hash, even though the accountInfo enrichment already carries the related public key. This PR shows the public key (and the saved account/contact name) when we have it, corrects the hash label, and makes long rows wrap adaptively.

Invariant preserved (WALLET-1251): the public key is sourced only from accountInfo.publicKey. It is never recovered from the address bytes (an account hash is a one-way blake2b hash of the public key). When enrichment is absent, the row falls back to the account hash. This is not a regression of the previous decoding fix.

Changes

• Show public key from enrichment (eip712-display-row.tsx): the account row passes accountInfo.publicKey to AccountInfoRow when present (fallback to the account hash). This also fixes, for known accounts, the explorer link, the identicon, and the saved-name lookup (which compares against publicKey and previously never matched an account hash).
• Correct hash label (account-info-row.tsx): new optional isAccountHash?: boolean prop. When set it forces the Account hash / Public key label instead of relying on the startsWith('01'|'02') heuristic that mislabels some account hashes. Default undefined keeps the existing heuristic, so all other screens that use AccountInfoRow are unaffected.
• Adaptive 2-row layout: RowDataContainer gains flex-wrap: wrap. Rows stay on a single line when there is room and wrap the value to a second, left-aligned line only when it would crowd the label (no forced column). Scalars (Value, Nonce, dates) stay single-row.

Method rename — signTypedDataEIP712 → signTypedData

Reverts the verbose signTypedDataEIP712 naming back to signTypedData, realigning the typed-data signing method with the existing signMessage / signDeploy convention:

• Provider method (sdk.ts): the public, dapp-facing method is provider.signTypedData(...) again.
• Action creators (sdk-method.ts) and their action-type strings (CasperWalletProvider:SignTypedData / :Response / :Error), the background and content handlers, and the ErrorMessages.signTypedData key.
• casper-wallet-core re-bump to 448c7cb, which renames the repository method to eip712Repository.signTypedData(...) (used in sign-eip712).
• Intentionally kept as-is: the public CasperWalletSupports.signTypedDataEIP712 = 'sign-typed-data-eip712' capability value.

Companion PRs: core make-software/casper-wallet-core#52, playground make-software/casper-wallet-playground#24.

Scope

The account-presentation changes are wallet frontend only — core already exposes row.accountInfo.publicKey, so they need no core change. The bundled method rename (above) additionally re-bumps casper-wallet-core to the signTypedData repository-method commit.

Testing

This repo does not unit-test React components (zero .tsx tests; testEnvironment: node; npm run test runs without --coverage), so changes are verified the established way:

• npm run ci-check — format, lint (0 errors), tsc, test (28 passed) all green.
• Manual (playground): Permit owner/spender show the public key + saved name for known accounts; unknown accounts show the account hash labelled "Account hash" with no false "Public key"; the TransferWithAuthorization package row is unchanged; long rows wrap only when cramped; signing a typed-data request resolves through provider.signTypedData(...).

Out of scope

• The subject == signer warning (still deferred from WALLET-1251).
