* dev: refactor core-profiler - modularise each page
- wrapped each page's pre, post, and main states into their top level states for tidiness
- tagged them with id so that we can easily jump to them when doing routing
- generalised component finder code such that it recursively traverses the state meta object until it finds a component key
- fixed css label to use top level state key
* moved initializing into introOptIn so it's not a special case by itself
