agentic: bump aiperf Configure Profiling timeout 900s -> 1800s

R3 H200 marathon hit aiperf's 900s Configure Profiling timeout on every
job (14/14). Root cause: H200 /tmp is ~3x slower than B300's, and 14
parallel jobs contending for the same shared /tmp pushed dataset config
(load + reconstruct + 62GB mmap + 4min inputs.json) past the 900s
budget. vLLM started cleanly in every case — aiperf itself timed out
during its own dataset materialization step.

Bump the timeout to 1800s (30 min) so worst-case slow-/tmp + contention
scenarios still fit. Post-setup measurement window unaffected.
