Use one blue for the menu bar on every page, refs #38206

The bar came in three shades: #2636d1 from nice_menu.css on hgTables,
hgBlat, hgc and the other cart CGIs, #00457c on hgTracks through its own
set of ids, and #003a72 on the gateway and the static pages, which
override nice_menu.css afterwards.  They are all #003a72 now, the house
deep navy already used for the gateway banner, the footer and the
buttons.

hgTracks no longer rewrites main-menu-whole and home-link into its own
ids, so its bar and its house icon come from the same rules as everyone
else's, and hgTracksHomeIconSprite.png goes away - the shared sprite is
white on a transparent background and sits on whatever blue the bar has.

gbStatic.css keeps its own copy of the color on purpose; the comment
there says why.
