fix(mpc-service): 重构数据库迁移机制，从根本解决表不存在问题

问题分析:
- 旧迁移文件只有 party_shares 表，缺少 session_states 和 share_backups 表
- Prisma 的 _prisma_migrations 表记录迁移已完成，导致新表无法创建
- 迁移状态与实际数据库不一致

解决方案:
1. 删除旧迁移目录，创建全新的 0001_init 迁移
2. 新迁移包含所有三个表: party_shares, session_states, share_backups
3. 添加 docker-entrypoint.sh 启动脚本，容器启动时自动运行迁移
4. 修改 Dockerfile 使用 entrypoint 脚本

deploy.sh 新增命令:
- migrate-reset: 重置数据库并重新运行迁移
- migrate-push: 强制同步 schema (创建缺失的表)
