Refactor/enhance history component

[derkoe]

There are different issues with the history component:

• The component does not update when the history changes - should be refactored to use an Observable
• The cookie reading/writing is quite complication and is done multiple time while changing the history - rewrite to have a single entry point.
• initializeCookieSettings is called every time a component is used (history and pinned history)
• Make max entries, cookie names, max age configurable
• Username should not be outside of the context, it should be just another context property. Maybe event better: flatten the context to a single string - the using party can concat this themselves.
• Handle links and iOS app mode correctly, when single history-items are located in different tlds due to modularisation.

Ensure that we keep the following design goal intact:

1. we need to ensure proper link styling!
   valid "a href" seems to be required for clarity to apply styling.

2. from ux-point of view we should enable the user to open a history-item in a new tab quickly
   ("CRTL+Click", "Left-Click > open in new Tab", ...)

3. App-Mode must be supported and UX must not be brocken on mobile devices.
   this includes having different tld in history-items.

Nice to have:

• if URL is in the current application's route then do not reload page but just open the route
