FE: Applications review + shortlist/select/decline (Decide) #631

Context

Part of the Bounty Operate to Payout milestone (v1 boundless, Decide). The organizer reviews applications and shortlists/selects applicants. Mode-aware.

Blueprint to mirror

• Hackathon organizer submissions management (components/organization/hackathons/submissions/*) + the org shortlist/select API.

Tasks

• Applications tab: list applications with proposal content (proposalShort/proposalFull, portfolioLinks, estimatedDays, qualifications, video), status, applicant.
• Actions (mode-aware): single-claim -> select one (POST .../v2/applications/select); competition -> shortlist N (POST .../shortlist); decline with reason (POST .../:appId/decline).
• Reflect the resulting state (selected/shortlisted/declined) and what the applicant can do next (submit).

Acceptance criteria

• Organizer can review + shortlist/select/decline applications; UI matches the mode (select 1 vs shortlist N).

Depends on

• Bounty data layer (organizer hooks); applies to APPLICATION_LIGHT / APPLICATION_FULL modes.
