- redirect to sign-in if we get a 401 when making an API request

- adds a "window-proxy" util so that we can override `window.*` operations in tests
- fix `gh-selectize` attempting to register event handlers when the component has already been destroyed
refs #5845
- add tests for `tag-settings` validator
- add validation for tag slug length
- fix display of error message when saving tag fails on the server
- add max chars text to description char count, remove error message as the count/input colour already indicates an error
no issue
- standardize on "{TestType}: {ModuleType}: {module-name}" for test description strings
- standardize on `{module-name}-test.js` for test file names
- fix deprecation notices for ember component unit tests without explicit `unit: test` or `needs: []`
issue #5841
- fix relative link checks in navlink url input component
- fix navlink url input component sending absolute URLs instead of relative URLs to action handler
- remove URL manipulation in navigation settings controller (url input handles URL manipulation, validator flags anything that's still incorrect)
- capture cmd-s in url input to ensure changes are actioned before save
- automatically add mailto: to e-mail addresses
- add gh-validation-state-container component so .error/.success validation classes can be applied to any container element
- add validation-state mixin that can be mixed in to any other component to give it access to validation status (used in gh-navitem component to keep alignment when inline error message elements are added)
- validate and display inline errors on save
- improve ember test coverage for navigation settings related controller and components
