Integrate InviteSDK rewards flow into citizen claim widget

[Copilot]

Adds @goodsdks/invite-sdk@1.0.1 to the citizen claim widget and replaces the Invite Rewards placeholder with a provider-first, viem-backed invite lifecycle. Claim and Invite Rewards now share invite validation, joining, and refresh state without changing claim behavior.

• Shared invite runtime

  • Initializes InviteSDK only for Celo/XDC and delegates reads, simulations, writes, error mapping, and collection to the SDK.
  • Loads invite user, level, invitees, pending invitees, and eligibility diagnostics.
  • Supports retryable loading, unsupported-network, disconnected, join, collection, and mutation-error states.

• Invite code and joining

  • Implements GoodWallet’s Base58 shortest-unused-prefix algorithm using InviteSDK.resolveCode.
  • Validates unknown, self, and already-joined invite codes before joining.
  • Exposes the same pending-safe join action from both Claim and Invite Rewards.

• Rewards experience

  • Adds reward education, verified-code creation, current-page sharing, pending/approved invitee status, diagnostics, and batch collection.
  • Shares the exact current page URL without host callback, route, or destination configuration.

const message =
  `Claim GoodDollar with me. Open this page and use my invite code: ${code}\n` +
  window.location.href

• Coverage and documentation
  • Adds Invite Rewards tab smoke coverage and updated screenshot evidence.
  • Documents supported networks, environment behavior, sharing contract, code generation, and collection lifecycle.
