fix(demo): migrate Reactive Resume to SeaweedFS, fix Kiwix/Apple Health

- Replace MinIO + Chrome with SeaweedFS (S3) + bucket init container
- Update Reactive Resume to v5 config (S3_* env vars, APP_URL, AUTH_SECRET)
- Fix Kiwix: smaller ZIM download, graceful fallback on failure, start_period
- Fix Apple Health: use InfluxDB ping() instead of deprecated ready()
- Remove stale RESUME_CHROME_TOKEN and RESUME_REFRESH_TOKEN_SECRET
- Add .yamllint config to relax line-length for compose template
- Update validate-all.sh to use local yamllint config and new image refs
- Update unit tests for createbucket service (replaces chrome)
