fix(torrent): harden metadata reuse and live peer telemetry

- reuse validated tracker-bearing metainfo without restoring direct web seeds - preserve Torrent file selection while making long paths scrollable and copyable - add lifecycle-fenced peer and seeder summaries to Properties telemetry - validate cache tracker metadata and cover malformed, stale, and path-copy cases
