fix(computer): close VPS viewer review gaps

[milind-soni]

Summary

Follow-up to #458 after review identified two still-relevant UI edge cases:

• release bot control before waiting for best-effort VPS tunnel cleanup, so a stuck cleanup request cannot leave the bot paused
• replace the stale VPS backend copy with the shipped Auto opt-in and secure live-desktop behavior

The Companion-exit finding from #458 is already covered more comprehensively on current main by the new lifecycle listener, so this follow-up deliberately does not duplicate that implementation.

Verification

• pnpm typecheck
• focused VPS renderer test
• clean rebase on current main

Summary by CodeRabbit

• New Features

  • Clarified that Auto can create or wake its managed VPS when automatic startup is enabled.
  • Clarified that the live desktop is accessible through the computer panel.

• Bug Fixes

  • Improved control release and cleanup when opening the desktop viewer fails.
