Add icon banner display option and refactor startup banner logic

- Introduced a configuration option `Display_Icon_Banner` to control the visibility of the startup icon banner.
- Refactored `ProcessStartupState` to utilize TUI for displaying the banner if enabled, falling back to a classic banner display otherwise.
- Added new methods for building the banner panel and icon grid for improved visual representation.
- Updated translations and resource comments to support the new banner features.
