Implement Problem Status Workflow

[Mkalbani]

Description

Add status lifecycle for problems (open → in-progress → resolved → archived).

Current Issue

• Problems are just "active" or "inactive"
• No way to mark problem as solved

Proposed Statuses

enum ProblemStatus {
  OPEN = 'OPEN',           // Accepting solutions
  IN_PROGRESS = 'IN_PROGRESS', // Solution being implemented
  RESOLVED = 'RESOLVED',   // Problem solved
  ARCHIVED = 'ARCHIVED'    // No longer relevant
}

Acceptance Criteria

• Add status field to MeshNode
• PATCH /api/v1/mesh-nodes/:id/status (owner only)
• Cannot submit solutions to RESOLVED/ARCHIVED problems
• When marking RESOLVED, must select winning solution
• Add status filters to GET /api/v1/mesh-nodes?status=OPEN

Files to Change

• src/mesh-nodes/entities/mesh-node.entity.ts
• src/mesh-nodes/dto/update-status.dto.ts
• src/mesh-nodes/mesh-nodes.service.ts
