feat(cycle): drop the standing disclaimer from the cycle-tracking settings card

The card carried a four-sentence non-medical notice at the top of the cycle
on-ramp. It goes, at the maintainer's decision.

The goal-specific caveat on the prediction surface is untouched: a profile set to
avoid pregnancy still gets the stronger "not a contraceptive method" copy, which
is chosen server-side by goal and shared with the native client, so nothing about
that path changes here.

Removes the key from all six locales and the now-unused icon import.
