feat(web): add search button to sidebar header + restore turbo globalEnv

Add a visible search trigger button next to the create-issue button in
the sidebar header, improving search discoverability (previously only
accessible via ⌘K). Search dialog open state is shared via a Zustand
store so both the button and keyboard shortcut work.

Also restores turbo.json globalEnv config (FRONTEND_PORT, etc.) that was
accidentally dropped during the monorepo extraction, fixing worktree
port conflicts.
