This pull request completely removes the Tizen.Applications.AttachPanel project and all of its associated source files, including the AttachPanel class, its internal implementations, interop definitions, event arguments, and enumerations. I have no feedback to provide.

🤖 [AI Review]

Reviewed — no findings.

Scope checked:

• All 11 AttachPanel source/interop/project files are removed; the PR-branch tree confirms no remaining paths containing attachpanel.
• Removal is backed by ACR TCSACR-654 and is consistent with the recent DevicePolicyManager / TEEC public-API removal pattern (deprecated module retirement).
• Packaging spec packaging/csapi-tizenfx.spec contains no AttachPanel reference, so the package build surface is not left dangling.
• CODEOWNERS still lists the path, but the prior DevicePolicyManager/TEEC removals left their entries in place as well — this is consistent with current project practice and not a regression introduced here.
