refactor: remove GenericManagePermissionsDialog and GrantAccessDialog components

- Deleted GenericManagePermissionsDialog and GrantAccessDialog components to streamline sharing functionality.
- Updated ManagePermissionsDialog to utilize AccessRolesPicker directly.
- Introduced UnifiedPeopleSearch for improved people selection experience.
- Enhanced PublicSharingToggle with InfoHoverCard for better user guidance.
- Adjusted AgentPanel to change error status to warning for duplicate agent versions.
- Updated translations to include new keys for search and access management.
