What happened?

Description

Craft appears to be delaying auto-generating the slug field until the first Save operation for entry types that don’t use the native title field. This leads to poor AX for asset fields that use {slug} in the upload path.

In the absence of a slug, Craft ends up creating temporary asset folders and any assets uploaded before the first-save end up remaining in these temp-xxx… folders, even after a slug has been generated for the entry (automatically by Craft).

Steps to reproduce

1. Create an entry type with an auto-generated title using a custom title field (example screenshot below)
2. Create an asset field with {slug} in the Default Upload Location setting.
3. Add this asset field to the entry type from step 1.
4. Create a new entry for the entry type from step 1
   • Upload a file to the asset field from step 2
   • Entry “Foo Bar” in the custom title field
   • Do not manually fill in the slug field
5. Save the entry

Expected behavior

Expected behavior is that the asset uploaded in step 4 will be saved inside a folder called foo-bar.

Actual behavior

Instead, the asset is found inside a folder called temp_eqzxinrledslkmppbcjqgtbddqemrexmtvem.
