Fixed: Input dispatching timed out in CoreReaderFragment.toggleBookmark.

[MohitMaliFtechiz]

Fixes #4127

• Moved the Book() object creation to lifeCycleScope instead of running it on the main thread. Earlier, it was blocking the UI, especially with large ZIM files. Now, by using lifeCycleScope, it won't block the main thread.
• Improved the KiwixServer creation process. Server creation was previously happening on the main thread, which could cause the same issue we are facing with adding bookmarks. Because we are creating the same book object while creating the server, which is required for server creation.
• Updated the behavior of the "Starting server" dialog. Before, the dialog disappeared after validating the IP address, even though server creation was still in progress. Now, the server creation process is moved to the IO thread. For large ZIM files, server creation can take some time, so the dialog will only dismiss once the server is successfully created or if an error occurs. This ensures users are aware that server creation is in progress.
