Fix search widget input width; remove dead navigation CSS

The input's width was calc(100% - 70px), a number tuned to leave room
for a "Search: " label that no longer needs to exist -- replaced by a
placeholder instead, which also removes the fragile arithmetic
entirely rather than re-tuning it. Also picked up a proper
border-radius and padding, matching the dashboard's own search input.

The width bug's actual proximate cause was a stray #navigation div {
float: left } left over from the old text nav, interfering with the
icon nav's own flex layout. Going through that whole block with the
same scrutiny turned up four more rules worth removing, not fixing:
a:hover (identical specificity, later in the file, silently winning
the cascade since the icon nav landed), and #metadata/#overview_toggle
in the remaining selectors were dead for two different, confirmed
reasons -- #overview_toggle was the old wizard's toggle bar, gone
along with it, and #metadata here was the pre-details-view subnav
toggle, retired before this session and unrelated to the current,
still-live #metadata id on the metadata-details section in nodes#edit
(a confusing reuse that's caused real problems before).
