test(evals): give the open-work inventory agent room after seeding 504 tasks

Run 42459254965 followed the long-list guidance: it saved all 501 open
tasks as a document on the conversation (an offline grade of that document
passes). The 600 s attempt ended 18 s after the final document write and
before the reply. Seeding and settling the inventory takes about 2.75
minutes of each attempt, so the agent had about 7 minutes. The attempt now
allows 900 s, the same budget as other large-setup chat cases.
