All 4 badge test files had identical ~35-line beforeEach blocks (pageerror listener,
inline V3 route mocks, addInitScript localStorage seed). Replaced with two helpers
in minimal_v3_mocks.ts:
seed_trusted_session(page, event_id, account_id?)
— seeds ae_loc localStorage with trusted/manager auth via addInitScript;
account_id defaults to testing_account_id
setup_badge_test_page(page, event_id)
— one-call beforeEach: pageerror listener + attach_minimal_v3_routes +
seed_trusted_session
Each test file's beforeEach is now 1-3 lines. All 12 tests still pass.
