. Add `api/client.ts` request timeout

[DeFiVC]

What: Add request timeout to the ApiClient to prevent hanging requests.

Why: Requests can hang indefinitely if the server doesn't respond. Timeouts ensure the app doesn't get stuck.

Scope: Add timeout parameter to ApiClient methods (default 30s). Use AbortController with setTimeout. Handle timeout error gracefully.

Acceptance criteria:

• Requests timeout after 30s
• Timeout is configurable
• Timeout error is handled
• No hanging requests

Technical context: src/lib/api/client.ts — ApiClient class. src/lib/api/ — API modules.
