docs: the runbook's settings inventory and the bench page's help links are current

BRINGUP named nine cool_* tunables (there are thirty), a cool_fire_ir_delta
key nothing reads, and panel source files that no longer exist; the
inventory is the present one. The bench page's help popovers pointed at a
documentation host and paths that do not exist; they open the site.
