Switching between /mints, /fedimints and /lnurl-mints showed the right list
for a moment and then flashed back to the previous ecosystem's mints. The
client router keeps every page's script alive, and onReady re-runs each
setup on every arrival, so a visited page's setup also ran on the next page.
All three grids were marked with the same bare data-mint-grid, so the stale
setup found the new grid, fetched its own type and overwrote it.
Mark and query each grid by ecosystem (data-mint-grid="cashu" etc.), the way
the home page already scopes data-home-grid, so a stale setup finds nothing
and bails. Skip the render in hydrateMintGrid when the grid has already been
detached by the router. Document the re-run-everywhere contract on onReady,
and add a static wiring test so a bare marker cannot come back.
