After a path animation completes, keeps an invisible clickable polyline
on the map for 30s. Clicking it shows a compact Leaflet popup with type
badge, hop chain, relative time, and a link to the full packets page.
Popup auto-dismisses after 20s.
## Changes
- `clickablePathsLayer`: new Leaflet layer for invisible hit-target
polylines
- `buildClickablePathPopupHtml()`: pure function generating popup HTML
(type badge, hop chain, time, hash link)
- `pruneClickablePaths()`: TTL (30s) + FIFO eviction (max 50); runs on
existing `_pruneInterval`
- `registerClickablePath()`: adds invisible polyline with click → popup
handler
- `animatePath()`: accepts optional `pktMeta` (`hash`, `ts`); calls
`registerClickablePath` on completion
- Teardown clears `clickablePathsLayer` and `clickablePaths`
