style(table): move the column picker into the table header corner

The show/hide-columns gear only makes sense in table view but sat in the
global toolbar (needing applyColsWrapVisibility to hide it elsewhere). Build
it inside the actions-column header cell in renderTable instead, with inline
handlers (recreated each render, so no dependence on once-wired listeners on
a static node). Removed #colsWrap from the toolbar + the now-obsolete
applyColsWrapVisibility and its callers; kept the menu id so
renderTableColsMenu still populates it, and a live-queried outside-click close.
Added .cols-wrap CSS (was an inline position:relative on the old node).
