fix(torrent): harden lifecycle and properties state

- admit valid magnets immediately while keeping metadata refresh optional
- fence Torrent recovery, diagnostics, and allocation presentation by lifecycle
- avoid false peer-wait claims when telemetry is missing or malformed
- stabilize Properties metric label/value layout for narrow and RTL windows

Tests:
- npm test -- --run
- npm run build
- npm run check:i18n
- node --test scripts/*.node-test.js
- cargo test --all-targets
- npm run smoke:torrent
- npm run smoke:torrent:failure-paths
- git diff --check
