chore(ci): run the bulk-email chunk/resume test classes in the push matrix

No job in the integration-tests matrix runs the tests/ root, only its
subdirectories and the explicitly listed files, so the attendee bulk-email
test classes added by this branch and the speaker chunk/resume classes
added by #595/#598 never executed in CI.

Add two path-named shards, one per subject, listing those files.
tests/AttendeeServiceTest.php stays out on purpose: its pre-existing
testRedeemPromoCodes hardcodes summit id 24 and fails on a fresh database.
