Build the Create-request form

[iexwr]

Context

src/pages/Create.tsx is a placeholder. Users need a form to create a payment request and get a shareable link.

Acceptance criteria

• Form fields: payee (prefilled from connected wallet, editable), asset (text input for SAC address, default XLM), amount, memo.
• Client-side validation (amount > 0, memo length) before submit.
• On submit, POST /api/v1/requests (or call the contract directly for MVP) and render the resulting shareable URL with a copy button.
• Shows inline error and success states.

Technical notes

• Use React Hook Form or plain controlled state; keep it dependency-light.
• Link format: /request/<id>.

Testing

• Component test: fill form, mock the API, assert the shareable link is shown.
