UI changes for the demo

[Raj6939]

• Add an Doc icon on top right of nav on the left of the profile icon, clicking on that should take user to https://docs.hypersign.id/entity-studio/introduction url
• On edit - “Update” button should come in all sliders
• In all sliders there should be a line before save/update button - see in Org its not there - what I am saying is try to maintain consistency.
• What is the date time format?? It should be (UTC) and all date time field column names should have mentioned “(UTC)”. For example: “Created At” should be “Created At (UTC)”
• Copy icon in all Ids (schema, credential)
• remove schema icon from “Schema”/“Credentials"/ “Presentation Template” headers
• add Schema URL in Schema Id and also copy icon in presentation template page, also where ever there is schema Id, DID and VCId - make them URL and add copy icons
• Remove truncation in template id in presentation template page - its not required
• There are lines in all the pages except on dashboard.
