Remove Truncation Limit for Device Notes in DVT

NetBrain currently truncates device note text within DVT once it reaches a certain length, and this truncation is present in both the Web UI and the Functional Portal, preventing users from viewing the complete note content. This enhancement would remove or substantially raise the character limit applied to device notes so that full note content displays consistently across both interfaces. Customers rely on device notes to capture complete operational context and troubleshooting details, and eliminating this truncation would ensure critical information remains accessible and is not silently cut off.
