feat(tables): a glyph pager with first/last, and tablet-width columns step aside

The pager is four named arrows round the page box (first, previous,
next, last). A table hides a tabletHidden column below 64rem of its own
width, as narrowHidden does below 42rem, through one shared helper that
also hides the column's <col>. The Channels table drops Prio, About and
Length there: at 1024 the channel name had 60 px.
