ci(desktop): run the live suite's lease-lapse test on its own runner

[waleedlatif1]

Summary

• desktop-live was the last check to finish in 46 of 57 recent clean PR runs and 14 of 14 staging pushes. It ran one 12-test spec serially in about 9.3 min (p90 10.7)
• 60% of that is two deliberately long tests that outlast the real 60 s execution lease and tool budget. The lease-lapse test alone takes about 3.1 min
• Split the job into a 2-way matrix: desktop-live (lease-lapse) runs that test via --grep @lease-lapse, and desktop-live (rest) runs the other 11 via --grep-invert. Each shard boots its own app, database and Electron, so the shards don't share state. Expected job time is about 6–7 min, below the mobile e2e chain (about 8.3 min)
• Expected savings: about 1.4 min median off checks / ci on PRs (all a desktop-live fix can save, since the mobile chain is then the critical path) and about 2.5–3 min off staging push → deploy
• Coverage is unchanged: every test still runs against the real lease and budget constants, with no test-only seams. A grep that matched nothing would fail the shard with "No tests found", so a renamed title can't silently drop the test
• The gate is unchanged: needs.desktop-live.result aggregates the matrix

Type of Change

• Improvement

Testing

• Timing from the last 120 ci.yml runs (job and step timings, finishing order); this PR's own CI run exercises both shards
• actionlint, biome
