CI: reset login rate limit between the auth and content e2e packs

The previous commit's "Auth e2e pack" job failed: auth.spec.ts's own
logins already spend a good chunk of the 10/min/IP login rate limit
(operations.md), leaving content.spec.ts's five more logins to hit it
mid-pack. Reproduced locally against a fresh throwaway database
(migrate + seed + both Playwright runs back to back, exactly the job's
steps) and confirmed a DELETE on rate_limits between the two runs
fixes it.

Follow-up to #32, not a new issue — the pack itself was already
correct, this is a test-infrastructure fix.
