[CLEANUP] Move internals

This is our big one. As discussed in #2111 we are going to move out the `include` and `templates` folder from our webroot. This is a major change and will require pool operators to:

* Move the global configuration file to the new location
* Run the upgrade script to set the new DB version to 0.0.9 (though nothing has changed, just to make sure)
* Use `git status` to fully cleanup the remaining directory structure
 * Ensure no files are still needed (configuration files, custom template updates)
 * Usually `rm -r public/templates public/include` will do the trick
* Re-confirm folder permissions for the `logs` folder since it will be used by website and crons now

I have deployed these changes to my DOGE pool for testing purposes and did not run into any issues. Will do the same for my FST pool since it actually finds blocks and I can test the backend that way too. Local testing was successful, no impact on my setup.
