Add submission mutation hooks (new)

[0xdevcollins]

Depends on: #100

The backend has three submission-related mutations (submitToBounty, reviewSubmission, markSubmissionPaid) that have no corresponding frontend hooks yet.

Tasks

• Create hooks/use-submission-mutations.ts with:
  • useSubmitToBounty() — calls submitToBounty mutation
  • useReviewSubmission() — calls reviewSubmission mutation
  • useMarkSubmissionPaid() — calls markSubmissionPaid mutation
• Each hook should invalidate the relevant bounty detail query on success
• Add submission query key factory to lib/query/query-keys.ts
• Wire the hooks into existing or new UI (bounty detail page's submission section)

Acceptance Criteria

• Users can submit PRs to bounties via GraphQL
• Org members can review and mark submissions as paid
• Bounty detail cache refreshes after submission actions

Hello, can I handle this?

I've gone through the requirements and can have this ready in under 24 hours. I have experience implementing GraphQL mutation patterns and cache invalidation strategies, so I’m familiar with ensuring UI states stay perfectly synced after contract-related actions.

I’ll tackle this by creating the use-submission-mutations.ts file and implementing the three hooks for submitting, reviewing, and marking payments. I'll use TypeScript to define the mutation logic and integrate the query key factory to ensure that the bounty detail cache automatically refreshes on success. Finally, I’ll wire these hooks into the bounty detail page so the submission flow is fully functional and provides immediate visual feedback to both users and org members.

Please assign this to me.
