test(sec): pin DocumentTextTools.ReadDocumentLines no-content guard (#…

…613)

Line 135 (the "has no content" early return when FileContent.Bytes is
null) was zero-hit. Mirrors the existing SearchDocumentKeyword no-content
pin for the sibling MCP tool: a document indexed before its body
downloaded must yield the graceful message, not NRE on
Encoding.UTF8.GetString(null) and surface as an opaque MCP tool failure.
