chore: shorten section label to 'Locations' so the divider stays consistent

"Pathway Browser Locations" was wider than the data column the
divider-name-container is pinned to, so the flex-grow lines on either
side collapsed to zero and the label sat flush left -- inconsistent
with shorter dividers like "Overview" / "Events" / "Authorship".
Tried widening the container so it sized to content, but that pushed
the label outside the content card's left edge on wide layouts.

Cleanest fix is just to use a label short enough to fit the existing
column width with room for the dashes. Context (the section content
lists where in the Pathway Browser the entity appears) makes
"Locations" unambiguous.
