Allow topic metadata to be viewed and edited

[knolleary]

Closes #5046

This PR targets the mqtt-topic-schema-storge branch that is delivered by #5053

Description

Adds the ability to view and edit topic metadata in the UI.

I expect some updates around tests to follow today.

[knolleary]

Just spotted the big commented out preHandler that needs updating - putting back to draft 😆

[knolleary]

Have fixed the perms check. Working on test failures now.

First pass of all the backend code looks good, bar the one comment about the type/inferredSchema bit.

UI looks good when testing, haven't looked too closely at the vue code.

Will review again when not draft

[knolleary]

Have improved test coverage when using the team-broker id. Happy for final review.
