Crawlbar layer actions

[marcelmoreau]

moved layer__actions out of the layer—calltoAction variant as we use these in all sorts of layers, not just a dedicated variant

after moving it, modified the styles so it doesn’t automatically center, and so we can account for more than one button, and have them spaced out properly, wrapping it they need to (especially on mobile) – these 2 buttons can now be seen on the homepage and on layer—calltoAction

layer__actions also needed a modifier so we can center them if we want (which I added into layer—callToAction.twig)

there was a crawler appearing on the homepage because of two issues:

• a grid blowout on .layer….seems this needs some sort of width so it doesn’t cause issues: see https://css-tricks.com/preventing-a-grid-blowout/
• footer’s contents were too wide

i’d like to re-do the footer completely at some point but it doesn’t cause crawlbar anymore

• moving layer__actions, and adding -centered are both great, make sense to me
• ~We can include the grid blowout fix, though I can only replicate this issue by editing the DOM via dev tools/inspector.~ Nope, sorry, my bad, I see it now, good catch let's include it.
• The footer definitely needs to be fixed, but comparing this PR's version to the existing version I'm not sure your version is going the right direction. I'd be more tempted to just do a simple fix on the existing version so that flex-direction is column for siteFooter__container and .linkGroups for small breakpoints, and change to use gap instead of left-margin (like you did in your PR.) Maybe add a gap: to .siteFooter__container too to space between the logo, nav, and social links.
