fix(create-object): update wizard template to use new API endpoints

[iamh2o]

Summary

Fixes the create object wizard page (/create_object) which was broken after the field name migration, and improves the file status message for files awaiting data.

Problem 1: Create Object Wizard Broken

The field name migration (PR #168) changed API endpoints from legacy BLOOM names to TapDB naming convention:

• /super-types → /categories
• /sub-types → /subtypes

And response field names:

• super_types → categories
• sub_types → subtypes
• sub_type_count → subtype_count

However, the JavaScript in create_object_wizard.html was not updated, so it was calling endpoints that no longer exist.

Problem 2: Confusing File Status Message

When a file instance is created without actual file data, the status was set to:

no file data provided or import is not 'import'

This message was confusing because it implied the import_or_remote setting was wrong when the actual issue was simply that no file data had been provided yet.

Changes

Template Fix (templates/modern/create_object_wizard.html)

1. Fetch from /categories instead of /super-types
2. Use data.categories instead of data.super_types
3. Fetch from /subtypes instead of /sub-types
4. Use data.subtypes instead of data.sub_types
5. Use subtype_count instead of sub_type_count

File Status Fix (bloom_lims/domain/files.py)

Changed status message from confusing:

no file data provided or {import_or_remote} is not 'import'

To clear:

awaiting file data

Testing
