The cached path-detail URL was a thinned-down view (geometry +
loss-budget summary + score). The user wanted the same rich display
/path renders — terrain chart with feet axes + tooltips, conditions,
scoring, link/power budgets, forecast — so PathShow now resolves the
row's rover/station/band/heights and push_navigates to /path with
those params baked in. The cached result map on Path.result is still
what the rover-planning show table reads from for fast row rendering;
this just bridges the row click to the canonical Path Calculator.
New /rover-planning/:id/paths/:path_id route renders the worker-stored
result map directly: geometry, link-budget components, propagation
score, computed_at. The 'Recompute live' button hands off to /path
when the operator wants HRRR-driven loss against current weather.
