Merge PR #102: feat: 支持漏洞关联多条流量证据

冲突解决:
- db/schema.sql: 复测表(#103)与流量证据表(#102)均为追加,两者保留
- server/server.go: 启动序列同时保留 seedFindingRetester 与 evidence GC
- web/src/lib/types.ts: InterceptAudit/InterceptDetail(#101) 与流量证据类型(#102)并存
- findings/detail/page.tsx: 去掉 #103 带入的重复 import,仅保留 FindingRetestPanel
- chat/page.tsx: 保留 #103 的 Spinner import
