Make manual eslint fixes

These are safe fixes, more complicated fixes can be done separately
(just disabled those errors for now).

- Reorder declarations to fix `no-use-before-define`
- Rename parameters for `no-shadow`
- Remove unused parameters, functions, imports
- Switch from `++` and `—` to `+= 1` and `-= 1` for `no-unary`
- Use object spreading instead of parameter reassignment in auth utils
- Use `window.location` instead of `location` global
- Use inline JSX strings instead of unescaped values
