Issue 1782 attachmentsdelete 403

Issue #1782 — api/attachmentsdelete: every attachment delete answers 403 NO_RIGHT (wrong attAuthOwnerAllowed() args)

Root cause

api/attachmentsdelete/index.php was calling attAuthOwnerAllowed() with the wrong signature: it passed the table name string as the 3rd argument, but the function expects an array context from attAuthResolveContext(). This caused the auth check to fail closed for every request.

Fix

Replaced the call with attAuthCheckOwner($db, $user, $realTable, $fkId, true) (write=true for deletion). This resolves the context correctly and applies appropriate permission checks.

Verification

• Admin session: POST /api/attachmentsdelete/index.php?action=delete with valid id/table/fk_id returns 200 {"status":"ok",...}
• DB: the attachment row is removed as expected
• Minimal change only to the affected call
