🚀 Pull Request: Implement usePayment Hook

Description

Implements the core functionality for the planned usePayment hook as outlined in the project roadmap. This hook wires up the @stellar/freighter-api to build, sign, and submit classic Stellar asset transfers (both native XLM and credit assets/trustlines) in a single unified hook lifecycle.

Key Changes

• **Added src/hooks/usePayment.ts**: Built the React hook managing lifecycle states (idle, submitting, polling, success, error), integrating signTransaction from useFreighter.
• Exported Types & Hook: Exposed explicit types (PaymentAsset, UsePaymentOptions, UsePaymentReturn) and the hook itself via the main index barrel file.
• Added Changeset: Generated a patch versioning note (.changeset/add-use-payment-hook.md) to automate the release process and changelog updating.

API Footprint

const { submit, status, hash, isLoading, isSuccess, isError, error, reset } = usePayment({
  destination: "GBXXX...",
  asset: { type: "native" },
  amount: "10",
  memo: "Thanks!",
  onSuccess: (hash) => console.log("Sent!", hash),
  onError:   (err)  => console.error(err),
});
