David Barragán Merino af1537d071 Shard integration e2e tests across four parallel jobs
Split the integration suite into four shards running two Playwright
workers each. Median wall time for the job drops from ~40 min to an
expected ~15 min; the build job is unchanged at ~4 min.

Shard reports are merged into a single HTML report, and the merged
run is summarised in the job step summary: totals, failed specs and
flaky specs ranked by retry count.

Chromium is installed into a shared volume so shards do not
re-download it. `workflow_dispatch` allows running the suite manually
against an arbitrary ref, with configurable shard layout and workers.

PRs targeting `staging` keep running serially while the current
release stabilizes. The exception is marked TEMPORARY and removed in
a follow-up.
