[frontend] batch-import.api.ts uses raw fetch with manual token handling — no refresh on 401

Bug Report

File: frontend/health-chain/lib/api/batch-import.api.ts

Problem

stageImport() bypasses the shared http-client and constructs its own fetch call with manual token retrieval:

const res = await fetch(`${base}/${PREFIX}/batch-import/stage?entityType=${entityType}`, {
  method: 'POST',
  headers: token ? { Authorization: `Bearer ${token}` } : {},
  body: form,
});

The shared http-client handles:

• Automatic 401 detection and token refresh
• Consistent error serialisation
• Request retry on transient failures

None of these apply to this raw fetch call.

Impact

• If the user's token expires mid-upload, the request fails with a 401 and the user must re-upload the file manually — no silent retry or refresh occurs
• If token is null (logged-out state), the request proceeds with no Authorization header and gets a 401 with no useful error message shown
• Error handling diverges from the rest of the app — the UI may show a raw HTTP error string instead of the standard error toast

Fix

Extend the http-client to support FormData / multipart uploads, then use it:

export async function stageImport(file: File, entityType: ImportEntityType) {
  const form = new FormData();
  form.append('file', file);
  return api.post(`/${PREFIX}/batch-import/stage?entityType=${entityType}`, form);
}

I'd like to work on this issue. I have strong experience with typescript, redis, docker, soroban and can deliver a clean, well-tested implementation.

My approach:

1. Analyze the existing codebase and understand the current architecture
2. Implement the solution following project conventions and patterns
3. Write comprehensive tests and ensure all existing tests pass
4. Submit a clean PR with clear documentation

ETA: within 24 hours

I'm available to start immediately and can provide regular progress updates.
