fix(web): keep sidebar toggle icon consistent

[voltcrash]

Summary

The main sidebar toggle changed from a static panel icon to a close-state icon when the sidebar was open, so the same control did not match its hidden-sidebar appearance. This keeps PanelLeftIcon in both states, matching the existing static bottom and right panel openers.

Verification

• vp lint apps/web/src/components/ui/sidebar.tsx
• vp run --filter @t3tools/web typecheck
• Integrated web pass verified the expanded and collapsed sidebar states and confirmed the bottom/right opener icons remain static.

After:

Implemented by opencode-go/gpt-5.6-luna via the OpenCode harness using T3 Code

• Style
