Add Explore Tab with Daily User Tracking / Analytics

Closes #168

Several things going on here (please forgive the scope creep / spillover), but they're all a bit interrelated and all good stuff. Puts in place the groundwork for the Explore tab, and all future features requiring communication with the server. Changes:

• Added "Privacy" SettingsCategory, with option for sending Daily Check Ins (default true) & info on privacy
• Added "App" SettingsCategory, with "Show Explore Tab" boolean (default true)
• Added Explore tab, from which can navigate to apps
• First app is Global Adoption which shows a graph / stats of daily active users
• Added Apollo & GraphQL, to communicate with the server.
• Added a bunch of missing translations, mostly zh_TW, as a result of running the translations scripts
• Added new "npm run go" command to spin up dev environment while ignorning new linters
• Some documentation changes in respect of these
• Fixed a bug where the Credits button was clickable outside (to the sides of) the expected button area because of some incorrect Tailwind classes/divs
