Remove two dead alias constants

SENSITIVE_LEAVES and COACH_SUGGESTED_ACTION_TYPES each aliased a
constant defined elsewhere and were never imported. Neither is a
re-export the way the barrel lines were — the definition itself is the
dead thing, and both doc comments describe a consumer that does not
exist: the purity guard reads SENSITIVE_LEAF_IDS from ./catalogue
directly, and nothing mirrors the suggested-action allowlist.

The imports that fed them go with them.
