Special layout handling for routes with groups

[razor-x]

• Hide preamble for resources on secondary route
• Filter resource samples that don't match filters

@razor-x An excellent step forward! A few things that I noticed...

• You removed the extra device overview from the thermostats page, but the overview also got removed (incorrectly) from access codes and unmanaged access codes.
• The alphabetization of the errors on the access code page is weird.

Also posted in Slack, but including here to keep them all together:

• The first device.properties prop on the thermostats page is an experimental prop that's marked as undocumented in seam-connect.
• How do I add descriptions for the capability flags?

@DebbieAtSeam

Will fix this before merge!

The alphabetization of the errors on the access code page is weird.

This is intentional. It's ordered by the parent resource that owns the error first, then the name. This will be addressed in a followup PR that groups the error by the resource. In this PR I mostly wanted to see if I could determine which resource the error was coming from.

The other two items will be answered outside of this PR.
