fix(dashboard): table width:auto so Character column sizes to content only

With width:100%, the table stretched to fill the container — and the
Character column (the only one with stretchable text) absorbed all the
extra space, looking much wider than the longest name needed.

width:auto lets each column size to its content. Table now fits its
data; container still scrolls horizontally if content ever exceeds the
viewport.
