test(qa): harden flaky geo + landing assertions to wait-for-condition

Two flake sources removed:
- geo_attendance_renders_eight_markers: waitForFunction($$ markers >= 8)
  with 20s timeout instead of a 3s fixed sleep. EA2 fetch + leaflet
  hydration race fixed.
- ceo_persona_dev_login_lands_on_landing + landing_exposes_all_hubs:
  waitForSelector(.hero-actions) + waitForFunction(hub-chip count >= 7)
  with 15s timeouts instead of 2.5s fixed sleep. Slow EA2 dev-login
  round-trips no longer race past hydration.

QA verified stable across two consecutive runs: 32/32 each.
