FE: Submit work flow (on-chain anchor) + withdraw submission

Context

Part of the Bounty Builder Lifecycle milestone (v1 boundless). After entry (claim/join/selection), the builder submits their work, which is anchored on-chain.

Blueprint to mirror

components/hackathons/submissions/SubmissionForm.tsx + SubmissionAnchorProgress.tsx
features/hackathons/api/use-submission-anchor.ts (participant anchor via the runner)

Tasks

Submission form: contentUri (PR / repo / writeup / demo link per the bounty's deliverable) -> submit escrow op (useEscrowOpRunner, participant, default MANAGED) + an anchor progress dialog (draft -> on-chain -> confirmed) with tx hash.
Withdraw submission (withdraw-submission escrow op) before the deadline.
Guard by bounty status + submission deadline + entry eligibility (claimed/joined/selected/shortlisted).

Acceptance criteria

Submit anchors on-chain and reaches confirmed; withdraw works; flows are correctly guarded.

Depends on

Bounty data layer; apply/join/claim flow.
