[Yaci-Viewer] - UI fix and enhancement

[wistkeylab]

On the current UI of yaci viewer v0.11.0-beta1, there's some text that hard to read because it's color is almost same with the backround.

Also for the transaction detail page, the UI is not user friendly and have different UI style with the home page.
