LEARNER-10340: Notifications Inbox Screen Error Handling

Following are the highlights of this PR:

PaginationManager: Introduced a new class to reuse the data fetching logic for a paginated API. It has been designed to cover as many use cases as possible while keeping the public API as simple as possible.
BackNavigationButton: Added support for insets to increase the tappable area of the button.
ScreenStateView: Created a custom view to show the current state of a screen.
NotificationsInboxView: Implemented pull to refresh, state and error presentation in the view.

Swipe-to-Refresh Implementation:

Added pull-to-refresh functionality to the Notifications Inbox screen for seamless updates.
On pull-to-refresh, retain existing notifications until new data is fetched successfully. If the fetch fails, show an error message at the bottom.

UI States and Messages:

No error message when unable to mark notifications as seen (background operation).
Show the empty state when there are no notifications.
Show the network error state when fetching the very first page fails due to network problems.
Show the server error state when fetching the very first page fails due to an issue on the server.
On a second-page fetch error, show an error message at the bottom.
On "mark as read" or "mark all as read" failure, show an error message at the bottom.
