This commit is expanding on previous work making everything chat working through an URL.
Improves drawer templates to be all URLs
Implements some kind of router for the drawer
Removes few remaining actions for opening channels
- Note this is also tweaking the UI a little bit as we are now using links/buttons in the header as needed
- It disables the find ideal channel in drawer mode, if loading `/chat` in drawer mode it will either reopen at the last position or just stay on index
