* fix(p2p stats): improve own-IP geolocation and world map accuracy Resolve the user's public endpoint when libp2p only advertises private listen addresses, look up an accurate country flag for "Your IP", snap peer markers to country centroids, and add leeching seeder link plus panel layout tweaks. * fix(p2p stats): skip caching own-IP lookups cancelled by abort When the P2P stats panel unmounts mid-request, its AbortSignal cancels the in-flight fetchOwnPublicEndpoint / fetchOwnIpCountryCode calls. Those empty results were still cached for 30-60s, so reopening the panel within that window showed "Your IP" as unavailable or without a country flag even though nothing had actually failed. Skip caching when the signal aborted so a later open retries. Addresses Cursor Bugbot finding.
