perf: analytics view and pricing availability edit have a median runtime over 30 seconds

Summary

On 5.3.x, two non-upload commands have p50 in the slowest duration bucket: asc analytics view (15 installs, 72.6% of runs ≥30 s) and asc pricing availability edit (10 installs, 56.3% ≥30 s).

What to do

• analytics view: likely synchronous report-request polling. Measure where the time goes; stream results as they arrive or expose --wait/--timeout semantics consistent with builds wait, and print progress on stderr.
• pricing availability edit: likely serial per-territory requests. Batch into Apple's documented multi-territory payloads where the API allows, or bound concurrency.

Acceptance criteria

• before/after timings in the PR body
• no change to output contracts
