Fix meta-row color regression, show Services/Activities as icon tags
The gray color from the previous commit landed on .gpx-popup__meta (the
whole row, label and value both) instead of just .gpx-popup__meta-label —
only the label was supposed to be muted, the value should read as normal
text same as the description above it.

While in there: Services/Activities were showing park4night's own raw,
comma-separated codes ("animaux, point_eau, wc_public"), which don't mean
anything to a reader on their own. PARK4NIGHT_TAGS (icons.js) maps the
codes p4n2gpx's exports actually use to a human label and, where the
National Park Service's icon set (already used for POI_ICONS) has a
reasonable match, a small icon — formatTags (gpx.js) renders each as an
icon+label tag instead of raw text. A code not in that table just falls
back to its own raw text, so nothing is ever hidden.
