This refactor addresses the following issues:
1- Moves all relevant logic to the discourse-topic component (matches desktop)
2- Fixes the flicker issue discussed here
3- Fixes a rare occurring issue where tags wrap to a third line if a topic has long category names and lots of tags
4- Fixes header icon jitter on iOS
5- Fixes an issue where sliding out user / hamburger menus on Android leaves the user in a mid-state with half a title and the header panel visible - swiping will now open the menus but have no effect on the header.
6- adds min-width to the small-logo to act as placeholder so that the title doesn't shift if the logo takes a while to load.
Other than that, everything should look and act the same.
