Consistent UUID display

Follow-up of #1108 (closed). The new worker run display modal introduces a new way of displaying UUIDs, which does not match the multiple other ways we have to display and use them, and on Whereby @babadie has stated we should make this the one way to display UUIDs.

Some quick notes without doing much research:

• UUIDs are used as the only link to a process' status in the process list.
• UUIDs are displayed in very small and very low contrast characters in the element navigation.
• The worker version details currently just have a Copy button and do not display the UUID.
• We should be careful when truncating a UUID as making it close to 7-8 characters makes it look like a Git commit hash and not an UUID.
• Discoverability issue: how to make it clear that an UUID can be copied on a click?
