Visually differentiate the wallet based on the network it is optimised for

User Story

As a user I want to be able to visually identify which version of the vega wallet i am using AND which network it is optimised for So that I can feel confident that I am using the right version for the task I am attempting to achieve

This is particularly useful for those users that are likely to have multipled version of the vega wallet installed AND will be beneficial for the project team to aid in the triage of issues that are reported

Acceptance Criteria

Wallet UI

• [ ] The name and version number of the wallet software is shown in the app header
• [ ] The frontend should be visually differentiated based on the network(s) the software is optimized for Vega Wallet, Fairground Wallet and Vega Wallet Dev.
