Tweak TPAC header layout styles

The TPAC header relies heavily on fixed pixel measurements and relative
positioning, which makes it fragile and overly difficult to customize.

To improve the situation, we can greatly reduce the number of styles
while still achieving the same overall effect.

match it on the right.

Touch-up record detail extras display

1) Remove unsightly gaps, which gave it an overly "stripey"
appearance.

2) Switch off-green arrow graphic with a text-based arrow character.

3) Simplify unnecessarily complex positioning styles.

4) Lighten and add subtle border to give depth and definition to
section headers.

Make sure that # can be used in auth browse

Because we use URLs to call the SuperCat browse API, we need to
be more careful about encoding parameters.  #, in particular, breaks
auth browse because it's seen as a URL fragment separator by the browser
and web server.
