Resource page table header cell layout inconsistencies

In our resource pages, we often have a table at the top of the page with info about the resource
instances ID cell is on left:

anti-affinity group ID cell is on right:

In #3260 we add it to the VPC page, on the left:

So there isn't currently a consistent layout placement for the ID, though it is in the last row on each of the pages.

There's also not a consistent practice around "created" date vs "last modified" date. Presumably, one is used over the other when it provides some added utility ("I just changed this resource; is that reflected in the last modified date?". With the change to the VPC page header (screenshot above), all datetime cells I could finds are on the right side, at least.

These aren't major, but could be worth thinking through so there's more consistency with them.

Start by comparing the resource page tables shown in the issue with the VPC page header. Determine a consistent placement for ID and datetime cells and whether “created” or “last modified” is the appropriate convention. Done means the convention is agreed and applied consistently across the affected resource pages.
