fix(api): remove duplicated model fields from DeprecatedPublishedAppTool

Fix incorrect merge from commit #403e2d58
which mistakenly duplicated `ToolFile` model fields and
placed them under `DeprecatedPublishedAppTool` class.

This removes the unnecessary duplicated fields to maintain
proper model structure.
