The tab code looks for the presence of a URL hash and calls showTab on a link with that href, without checking that the link A) actually exists and B) is a tab as identified by the data-tab attribute. As a result, non-tab-related uses of URL hashes (such as simply visiting /admin/#foo) throw a JS error.
Fixes #7146 - the root StreamField element is now matched by ID _and_ having a data-block attribute. (Duplicate IDs are invalid HTML and the 'proper' fix would be to add a global prefix to form fields, particularly since this problem isn't necessarily specific to StreamFields - but that would be a bigger breaking change.)
- Run `npx -p @storybook/cli sb init --type react --builder webpack5`
- Moved .storybook and stories folders into client
- Run `npm i --save-dev html-webpack-plugin@latest` to workaround https://github.com/storybookjs/storybook/issues/13332
- Add storybook-static to .gitignore
Fixes #7086. As per https://github.com/wagtail/wagtail/issues/7086#issuecomment-826945031, ensure that .as_data() is consistently called when telepath-packing ErrorList objects (so that we preserve any embedded ValidationError objects instead of casting them to strings), and introduce an explicit ValidationError class on the client side to make mismatches more obvious (and for future extensibility in case we need to attach more fancy logic to ValidationError).
Also add tests for setError, and fix rendering of StreamBlock non-field errors (selector to clear old errors was incorrect, and jest apparently doesn't support innerText).

Fixes #7083. Override default FieldBlock / BoundWidget behaviour so that:
* BooleanBlock.get_form_state bypasses CheckboxInput.format_value (which Django uses to determine the 'value' HTML attribute rather than the checked state)
* BoundCheckboxInput.get_state / set_state / get_value work with the 'checked' attribute rather than 'value'
* Add warning to bottom of draft comments
* Add a warning to bottom of edited comments
* Add a warning at the bottom of comments with unsaved replies
* Set role="status" on the comment notice
