Optimize tiles view

[tbsbdr]

Description

The tiles view is an eyecatcher in every demo situation; still there is a visual flaw: On many screens quite big whitespace shows up on the right:

Steps to reproduce

1. create 10+ resources, switch to tiles view
2. resize the browser window until
3. whitespace shows up on the right

Expected behavior

• regardless of the browser size, there should no extra whitespace show up on the right
• See video from box attached how the expected behaviour is

Actual behavior

• whitespace shows up on the right

I think the problem is that we need to resize the tiles in that case in order to fit on the screen, let me take a look
