fix: Populate HTML Page URL from identifier when field has defaultValue

[Millertaker]

Proposed Changes

• Fixed HTML Page URL being incorrectly overwritten by the Content Type's defaultValue during workflow actions (e.g., Publish)
• Added logic in ESContentletAPIImpl.find() to populate the URL from identifier.asset_name when the URL field has a defaultValue defined in the Content Type
• Added integration test test_find_HTMLPage_URL_ShouldBePopulatedFromIdentifier to verify the fix

Checklist

• Tests
• Translations
• Security Implications Contemplated (add notes if applicable)

Additional Info

Issue: Fixes #33893

Root Cause: For HTML Pages, the URL is stored in identifier.asset_name, not in the contentlet table (text3 column is empty). When loading an HTML Page contentlet via find(), if the URL field in the Content Type has a defaultValue defined (e.g., "test"), that default value was being applied instead of the actual URL from the identifier. This caused the Publish button on the Page Edit screen to overwrite the user-typed URL with the default value.

Fix Location: ESContentletAPIImpl.find() (lines 441-454)

Behavior:

• Only applies to HTML Page contentlets
• Only triggers when the URL field has a defaultValue defined in the Content Type
• Retrieves the correct URL from identifier.asset_name and sets it on the contentlet
