Obs merge issue

[B3RN153]

• Updated isomorphic git to fix the UI not displaying issue.
• Blocked OBS Combined Audio Export from being imported.
• Added functions to handle new import, replace and merge of OBS Default Audio Export.
• In New Project and Replace all exported will be imported as storynum_verse _1_default.mp3 into the project.
• In Merge if any verse has no audio and corresponding verse has audio in the import it will be imported as storynum_verse _1_default.mp3
• Added functions to handle new import, replace and merge of OBS Complete Audio Export.
• In New Project and Replace all verses will be extracted from zip and imported into the project.
• In merge missing verses and takes will be merged into the project handling default conflict, where incoming default suffix is disregarded.

Test Results:

1. The text merge import issue has been resolved in this PR.
2. When a user exports the project in Complete (Audio + Text) format and imports it back, it works as expected.
3. During merge, any missing verses and takes will be merged into the project.
4. When a user exports the project in Complete (Default Audio + Text) format and imports it back, it works as expected.
5. In the merge process, if a verse has no audio in the existing project but the corresponding verse in the imported file contains audio, the audio will be imported.
6. Blocked OBS Combined Audio Export from being imported.
7. The UI display issue caused by isomorphic git is fixed, and the Sync page for both BT and OBS projects is working fine

"All three export types, except the combined merge export, are working as expected for all import merge scenarios."
