`assets` already carried latitude/longitude, but `sites` had nowhere to put a
pin — so there was no way to locate a site. Both fields added, matching the
plant collection's shape so the same map component can plot either.
Coordinates are entered as two plain number fields with an "open in maps" link
to verify the point, rather than a drag-to-pin map: the in-app Leaflet map is
still being worked on, and a coordinate is usually copied off some other map
anyway. Clearing removes the pin rather than leaving half a coordinate, which
would plot in the Gulf of Guinea and read as "located".
Bounds are checked server-side, not just in the form: a point outside South Africa
is refused with the numbers echoed back, because a swapped pair or a dropped
digit is far likelier than a machine abroad. 0,0 is rejected by the same rule.
The sites list marks each row as pinned or "no pin", with a banner counting the
gaps, so an unlocated site is visible without opening it.
While checking this, found that all 44 assets carry the SAME coordinate
(-26.1016, 28.3487) — the Plant Map currently stacks every marker on one pin
while reporting "44 located on the map". Left alone, but worth knowing.
