Create TUI for vet with Common Styles and Design Language

[abhisek]

vet currently have a combination of internal and reporter specific interface that uses fragmented design language.

We need to separate the UI from vet core and refactor it as an independent concern that is:

1. TUI by default
2. Supports CSV, JSON etc.

Similar to what we have implemented in https://github.com/safedep/gryph

Important:

• Must define a common design language
• Must support both light and dark mode with auto-detection
