Bugs: clear compare params on tab change, recover channel live messages after a 429,
observer copy link keeps only region params, route table no longer navigates on region
change with nothing selected, map borders memo on data identity, live overview can't
resurrect a failed query, French relative times, no language write on first visit,
0/0 node locations hidden outside the map, path/signal stats use the shared retry rule.
i18n: node/packet/mesh/observer strings that were still hardcoded after #62.
Cleanup: formatUtc, ACTION_BUTTON_CLASS, observer-stats, useWindowedStats, observer-id;
observer pages use StatCard/Card/Field/Segmented/SearchBar/SelectDropdown; one details
chrome on the stats tabs; comment and translations-guide trims; localStorage stub for
Node 26 in the test setup.
* feat: replace getScopeStats with getScopes and update related tests
bug: lastSeen/sentAt was set to string instead of number by mistake
* feat: update timestamp handling and formatting across components
- WS messages carry epoch ms now instead of ISO strings
- new Timestamp component (relative/absolute), used in RouteTable and RouteDetailPanel
- IataChip and ScopeTag chips
- TraceDetailPanel and TraceList for trace drill-down
- tests updated for the timestamp change
