INJIWEB-1640 Fix mobile sidebar default open state after login

[iamlokanath]

Initialize the sidebar collapsed on mobile viewports so that, after login,
users land on the home screen with the sidebar closed by default, while
keeping the existing behavior (open by default) on larger screens.

Walkthrough

The Sidebar component now intelligently initializes its collapsed state based on viewport width. A mobile breakpoint constant (640px) and initialization function were added, with SSR-safe fallback handling to determine the initial sidebar state during page load.

Changes

Cohort / File(s)	Change Summary
Responsive Sidebar Initialization inji-web/src/components/User/Sidebar.tsx	Added MOBILE_BREAKPOINT_PX constant (640px) and getInitialSidebarCollapsed() function to dynamically set sidebar's initial collapsed state based on viewport width. Function includes SSR-safe window checking to gracefully handle server-side rendering contexts.

Poem

🐰 A sidebar so clever, it shrinks with the screen,
On mobile devices, it knows just what's seen,
With a hop and a bound at 640 wide,
It collapses on load, fit snug by your side! 🎯
