Fix widget attrs being dropped from rendered inputs, and redesign the referee PDF

field.html's "input" branch rendered type/class/name/value/placeholder only,
silently dropping every other widget attr -- so a NumberInput's step="any"
(added to let the per-km rate take values like 0.083) never reached the page,
and the browser fell back to whole-number-only validation. Pass widget attrs
through the same way the "select" branch already does.

Also gives the referee payment PDF a proper visual pass (accent header, an
info card for the game details, a real fee/km table with a grand-total row)
instead of the plain label/dotted-line layout, and lets the dashboard tile
show assigned referees with a "referee form" download button per tile.
