ci(st): expand list of full suite triggers (#112299)

#112293 didn't select anything
in sentry or getsentry dispatch for src/sentry/options/defaults.py -
this kind of stuff is evaluated at module load (before any test context
is active) so we don't have coverage data for it

added `src/sentry/options` FULL_SUITE_TRIGGERS and also had claude audit
for more stuff to put in there
