Update Layout of RccFullPage #37wu3jh

This issue is about making the home page look as in the new layout, visuals see below:

RccFullPageComponent is used in HomePageComponent and governs the looks of the home page.

This issue depends on these other Issue:

• #202
• #204
• #199

If all of them are ready, go ahead :)

What is to be done?

Only update RccFullPageComponent for bengal theme.

• Add a header including the logo (rcc-logo, #199) and a menu button, use dummy icon for now
• Add slot for content projection (https://angular.io/guide/content-projection) and have HomePageComponent insert date and greetings.
• Arrange the list of RccActionButtons, so that they look as in the layouts, see belows.
• Respect the different screen sizes

Requirements

• Home page looks like the images below when bengal theme is loaded
• Home page looks like before if default theme is loaded
• Date and greetings are projected

Note: Don't mind the colors and icons, the content is determined elsewhere, as are the colors of the buttons.
