dashboard: also remove the tombstone revive trigger

mara asked on PR #3854 to remove the revive action alongside the
blank-name spawn form. Both posted to /api/request-spawn as the last
two frontend callers; with this the dashboard has no UI path left that
hits that endpoint (backend removal/decision stays damocles's call).

Drops the K3PT ST4T3 tombstone row's ⊕ R3V1V3 form, leaving PURG3 as
the only per-tombstone action. Updated the two doc/comment spots that
described the now-gone button.
