Add monoline icons to the topbar coordinates/sun readout

WAYPOINT_ICON (coords) and PENDING_ICON (countdown) reused as-is; two new
hand-drawn SUNRISE_ICON/SUNSET_ICON since NPS's symbol set has no match —
same currentColor stroke style as the rest of icons.js, so they render
monochrome in the dark topbar rather than colored emoji.

sun.js's formatSunInfo now returns {sunrise, sunset, countdown} instead of
one joined string, so map.js can place its own icon in front of each
piece instead of the module owning any markup.
