Create shared useSidebar hook to centralize sidebar width and transition
logic, addressing code review feedback about duplicated logic between
Sidebar and HomeLayout components.
Changes:
- Add useSidebar hook with collapsed state, width, and transition values
- Update Sidebar to use the hook instead of inline selectors and values
- Update HomeLayout to use the hook for spacer element styling
This ensures sidebar width logic is defined in one place and stays in sync.
