feat(ui): Full pages for post submission and reporting, toolbar API fixes, debug toolbar

[ashquarky]

Resolves #77

Changes:

• Moves the reporting and new post modals on portal/ctr to their own full pages rather than popovers. This allows rationalising the client JS (removing postModules) and using the ctr toolbar API.
• Adds report button to replies on ctr.
• Slim down the toolbar API to the required functions only and apply it to every page. Should make toolbar state more consistent.
• Add a rough simulation of the 3DS toolbar to debug.js. Allows testing of toolbar behaviour in a modern browser.

• I have read and agreed to the Code of Conduct.
• I have read and complied with the contributing guidelines.
• What I'm implementing was an approved issue.
• I have tested all of my changes.
