refactor(cron): drop the status segments -- the column menu already does that

With per-column filters the page carried two filtering UIs for the same thing:
a segmented All/Active/Failed/Paused row, and the Status column's own menu with
live per-value counts. The segments were the weaker of the two -- fixed
buckets, no combining, and invisible in the chip bar -- so they go.

The presets that used to set the segment now carry real column rules, which
also makes them combinable with anything else you filter on. `status` gains an
explicit `value` accessor and `type: 'enum'` so filtering and grouping key off
the label the pill shows rather than an inferred guess.

Same duplication exists on Servers (status + group), Services and Workspaces;
those follow.
