wltcontract: curated contract-label registry + verifyingContractLabel

Adds the contract-label registry tibaneapp asked for to surface
"Uniswap V3: SwapRouter02" / "OpenSea: Seaport 1.6" etc. above the raw
0x… on typed-data approval sheets. Mirror shape to wlttoken/curated —
per-chain JSON files baked in via go:embed, sync Lookup helper, no
runtime network dependency.

Initial coverage (one per chain unless deterministic-address):
  Uniswap V2 Router (1), V3 SwapRouter + SwapRouter02 (1, 8453,
  42161, 10, 137), Universal Router + Permit2 (every chain;
  deterministic addresses), OpenSea Seaport 1.5 + 1.6 (1, 42161, 10,
  137; deterministic), Aave V3 Pool (1, 8453, 42161, 10, 137, 43114),
  Compound V3 Comet contracts (1, 8453), Balancer V2 Vault (1, 42161,
  137), Curve 3pool (1).

Wired into newMessageSignValue (wltbase/sign_request.go):
MessageSignValue gains a VerifyingContractLabel field, populated from
the registry when the EIP-712 domain has a verifyingContract that
matches. domain.chainId normalised across the shapes dApps actually
send (JSON number, float64 from json.Unmarshal default, decimal
string, hex string, 0x-prefixed hex). Empty when no match — host
falls back to the raw address.

Generic primitive: Contracts:lookup endpoint + Dart ContractsApi
wrapper so hosts can label addresses at any render site (effect
rows, watch_asset prompts, the new explorer-link affordances) using
the same registry.

Tests cover: address case-insensitivity, deterministic-address
cross-chain matches (Permit2), chainId shape normalisation, all the
"miss" paths (unknown contract, unsupported chain, non-EVM,
malformed domain).
