Updated the `isRouteActive` check in the sidebar component to ensure it doesn't falsely identify nested routes as active. Additionally, introduced a `PageBody` wrapper in the account page component for consistent styling and padding.
Refined both admin and marketing layouts for a clearer design. Newly added components for the admin page include admin-account-page, admin-members-table and admin-memberships-table. Also included in this update are route renaming, minor text edits and corrections in the code.
