<feature>[log]: add LongText type for logging long content safely

Add LongText type to NoLogging annotation to handle long content
like base64-encoded image data in logs. When content length >= 20
characters, only show first 10 and last 10 characters with ... in
between to improve log readability.

Applied to:
- APITakeVmConsoleScreenshotEvent.imageData
- TakeVmConsoleScreenshotReply.imageData
- KVMAgentCommands.VmHostFileTO.contentBase64
- KVMAgentCommands.TakeVmConsoleScreenshotRsp.imageData
