refactor: render the conky template from the dashboard repo

The Lua dashboard lives in conky-theme-udt now, so udt-palette renders
that repo's conky.conf.in instead of a local template and install.sh
links the Lua alongside the config.

gen_conky also substitutes critical, for the dashboard's error overlay:
conky reports a Lua fault as a blank window, so the dashboard catches
it and draws the message instead.

The old variables-and-execi template is deleted. Its hardware discovery
was not lost; the hwmon glob-by-name approach is carried into
lib/data.lua deliberately, since fixed indices drift across kernel
reorders.
