Setup basic App layout ready for workspaces/panels

[Greg-Nexus]

Chore

Requirements

The basic layout and structure of the App needs updating to ensure:

1. we are accurately reflecting features and functionality that are available to users.
2. existing pages are in a layout that is compatible with workspaces/panels

We will be removing:

• the 'Newsfeed' page and left-menu item, defaulting the "Home" page to 'My Games'.
• the 'Browse Games' page and left-menu item.
• the 'Search' bar from the UI.
• the 'Help' icon from the UI.
• the 'Settings' icon from the UI.
• the 'Home' icon from the spine menu.

We will be adjusting the layout of the menus (top, left and spine) so that they work with workspaces/panels.

Further issues will be moving existing pages into workspaces/panels, for the purposes of this issue these pages can be kept largely the same and moved into a container.

Design

Stripped down layouts are now available in Figma, these layouts will only show functionality that is either completed or in progress:

Going forward placeholder content will be marked with a red cross pattern to clearly indicate that it is not to be built. These frames will also be labelled "Placeholder content - ignore"

Acceptance Criteria

[Pickysaurus]

Can we please make sure "Plugins" is called "Load order"?

That way it can be generic across all games with load order-able entries rather than specific to Bethesda titles.

Input from Luca|EzioTheDeadPoet: mark them in the UI as game specific tools while the game that uses them is active (or with Bethesda games add a tooltip to the indicator that also shows other games that use the tool/feature). So even without a modding guide you will know that the tool won't be visible for some other games.
