Summary

This PR adds an API endpoint to expose contributor submission status, partially addressing #1056 (Proposed work: expose contributor submission status).

Changes

• Add GET /api/v1/accounts/{account}/submissions endpoint in app/accounts.py
• Return account info, GitHub login, submissions array, and summary counts
• Initial implementation with basic structure; full data integration pending

Why This Helps

• Contributors: Can track their open submission pipeline (submitted, blocked, accepted, pending payout, paid)
• Agents: Can query submission status without source-code inspection
• Maintainers: Have a foundation to build upon

Current Implementation

The endpoint currently returns:

{
  "account": "github:username",
  "github_login": "username",
  "submissions": [],
  "summary": {
    "submitted": 0,
    "blocked": 0,
    "accepted": 0,
    "pending_payout": 0,
    "paid": 0
  },
  "note": "Initial implementation. Full submission tracking pending database schema and GitHub API integration."
}

Next Steps

To fully address this issue, we need to:

1. Query database for open PRs by contributor
2. Integrate with GitHub API to get PR status (open, merged, closed, blocked)
3. Check for duplicate/withdrawn/needs-info/conflict status
4. Return maintainer acceptance and pending payout evidence
5. Link to proof-backed paid work

This PR provides the foundation and API contract. Feedback welcome on the approach and next steps.
