test(e2e): drive agent lifecycle via profile sidebar primary action

The mesh-compute restart spec still drove the old per-row agent-actions
dropdown (managed-agent-actions-<pubkey>), which PR #1200 removed in favor
of a Manage button that opens the profile sidebar. Rewrite the helper
(openManagedAgentActions -> triggerManagedAgentPrimaryAction) to click
Manage and then the user-profile-agent-primary-action toggle, preserving
the test's intent. Test-only; no product code changed.
