Implement SEP-24 Anchor Deposit and Withdrawal Modal Flow

[Cjay-Cyber-2]

Description — what to implement and the why/impact.

Users need a reliable interface to deposit and withdraw fiat currency into stablecoins (like USDC) via Stellar SEP-24 anchors directly within the neobrutalist UI. This task implements the anchor modal flow, connecting user wallets to registered SEP-24 interactive anchor endpoints.

Context & Requirements — background, constraints, design references, edge cases;

• Grounded in src/components/ui/ primitives and src/lib/types.ts for network communication.
• Must handle popup or embedded iframe interactions required by SEP-24 interactive transfer specs.
• Must gracefully manage network errors, anchor unavailability, and session timeouts.

Acceptance Criteria — a checklist ("- [ ] ...") of specific, testable conditions that define "done".

• SEP-24 deposit and withdrawal modal components are implemented with neobrutalist styling.
• Integration with API/anchor configuration fetches valid interactive transfer URLs.
• Proper handling of modal close events and transaction status polling.
• Unit tests for anchor URL builder and state reducer logic.

Implementation Guidance — likely files/modules to touch and a suggested approach.

• Touch src/components/anchors/ (or create if needed) and integrate with API hooks in src/lib/. Refer to Stellar SEP-24 specifications for parameter encoding.

Testing & Validation — how the contributor should prove it works.

• Run npm test and npm run typecheck to ensure type safety and test coverage.
• Manual verification of modal open/close states and form validation.

Submission Guidelines — must open a PR that includes "Closes #"; assignment is required before starting.
