Fixed: application was crashing when starting the kiwix server.

[MohitMaliFtechiz]

Fixes #3845

• Added a check for checking the MANAGE_EXTERNAL_STORAGE permission when starting the server in the non-playStore variant. If there is no permission, then it asks for permission to avoid the crash due to permission lack for file.
• Improved the permission asking when the user tries to start the server in all variants and all versions of Android so that it will ask storage(read/write) permission for below Android 13 in non-playStore variant. Also, ask for the MANAGE_EXTERNAL_STORAGE permission in Android 11 and above. This check ensures that without the storage and MANAGE_EXTERNAL_PERMISSION user can not start the server. Because if the application does not have storage permission then it crashes when creating the Archive object.
• Fixed: application crashing when hosting the split zim files on the server, since we have an issue with split zim files of zim-tools Zim-tools version 3.3.0 splitted zim files giving Corrupted block detected error when there is a 0 size extra ZIM chunk. #3827. Due to this issue, there is a crash reported on the playStore. Because we have full access to files in the playStore variant since all the files are located in the app-specific directory.

@MohitMaliFtechiz So we agree that this bug appears only if we have an empty chunk ofmzim file?

@kelson42 Yes, in the PS version this bug only happens if there is an empty chunk. For the non-PS version, there is this type of error because of a lack of permission(if the user intentionally disabled the permission) so here in this PR, we are fixing both issues.
