feat: Registry-verified badge + registryData data flow + V3 error recording
- ClinicSnapshot.tsx: 'Registry 검증' badge (ShieldCheck icon), district/branches/brandGroup pills, external links (강남언니/네이버플레이스/구글맵) when source=registry
- report.ts: add source and registryData fields to ClinicSnapshot type
- transformReport.ts: ApiMetadata now accepts source/registryData; passes to clinicSnapshot
- useReport.ts: DB load path extracts scrape_data.source + scrape_data.registryData → transformApiReport
- V3 dual-write error recording: discover-channels, collect-channel-data, generate-report now write error_message + error status to analysis_runs on catch instead of silently swallowing
