feat: combine session actions into options dropdown
SessionCard desktop view:
- Retain primary action button: Open (active) or Start (inactive)
- Replace individual Stop/Tunnel/Delete buttons with a single Options
dropdown triggered by a ⋯ button
- Dropdown contains applicable actions:
- Active: Stop, Recreate Tunnel (web), Delete
- Inactive: Start, Delete
- Add window.confirm before Delete as a safety net
- Dropdown closes on outside click or Escape key
- Add 'more' icon (DotsThreeVertical) to icon component
- Add session-options-dropdown CSS with subtle animation
Mobile view unchanged (already uses MobileActionSheet).
Quality gates: tsc --noEmit pass, npm run build pass, 82/82 tests pass
