fix(files_sharing): global search in sharing tab

[ShGKme]

• Resolves: clicking Global Search breaks the sharing tab

Summary

• Probably a regression from new flow: Improve sharing flow #39472
• In the past, on select it (in addShare):
  1. Checked if it was not the lookup = global search option
  2. Checked if it was not the external with custom handler option
  3. Created a share with default params
• Then it was moved to a new create share details view
  • onSelect now simply opens the details view where the share can be created
  • p.2 is also moved to the SharingDetails
  • p.1 was missed

TODO

• Migrate to new built-in NcSelect label
  
• Remove old now unused addShare method
• Restore lookup select processing

This breaks cypress tests.
I agree we do not need the ID but then you need to change the selector in the Cypress tests.
