Redirect User After Login

[ItzNotABug]

This PR adds the capability to redirect users to their initially requested page after a successful login.

---

Flow :

• User tries to navigate to /analytics/somePostUUID
• User is infact redirected to login because their session isn't valid
• After a successful login, they are redirected to /analytics/somePostUUID automatically

---

This eliminates the need to navigate back to the intended page manually after logging in.
