desrosj e7387a9ace Script Loader: Fix PHP notice caused by the `viewScript` for the `core/file` block.
This fixes a PHP notice caused by the `viewScript` for the `core/file` block having `.min.js` instead of just `.js`.

`register_block_script_handle()` was incorrectly looking for `view.min.asset.php`, which does not exist, and caused the `_doing_it_wrong()` notice.

This adds a check for `.min.js` in the `viewScript` field of `block.json` and corrects it to `.js` in order to match the expected pattern of `view.asset.php` until a more permanent fix can be created.

desrosj 6fc65b33d5 Script Loader: Use the provided block version when registering styles.
This updates `register_block_style_handle()` to use the `version` value provided in the `$metadata` parameter for non-Core blocks (when present). This removes the requirement to use `filemtime()` to generate a unique version.

When `version` is not defined within `$metadata`, the script version will fallback to using the current version of WordPress.

The block version should be considered similar to the one specified by plugin developers within the header of the main plugin file.

Make sure the `$sidebar` variable is defined and has at least one entry in the array, before adding the `.below-entry-meta` class to elements below the entry meta.

Previously, the theme expected sidebar markup to exist on the page if sidebars are defined, but that markup is missing since only the widget itself and headers/footers of the page are loaded in the iframe used to display legacy widgets (widgets added prior to WordPress 5.8).

desrosj 516bc482bd Editor: Prevent block stylesheets from loading when they do not exist.
This fixes an issue where block stylesheets were being loaded even if they did not exist, causing 404 errors. The issue presented itself when the site was choosing to load block assets individually through the `should_load_separate_core_block_assets` filter hook.

This also fixes an issue where non-Core blocks would only be registered if they actually had asset files. This prevents developers from adding additional information to a style handle, such as inline styles through `wp_add_inline_style()`.

This wraps the inner-content of the Site Health dashboard widget to give a unique target for CSS selectors, restoring the ability to collapse the widget.

The initial implementation targeted the `.inside` class used by all widgets to apply styling to the widget content, but this prevented the widget from being collapsed, as it added grid-styles which other widgets do not use, overriding the usual behavior when toggling widget visibility.

youknowriad 578cda50a2 Block Editor: Do not load a default font family for themes with theme.json.
This matches the behavior that has been in place in the gutenberg plugin.
The idea is that this makes the editor match the frontend by default for these themes.
If they use a custom font, they'll have to provide it for the editor as editor styles.

Props nosolosw.

desrosj 767be550d7 Widgets: Fix an “Invalid value” warning when adding a new widget in the Customizer.
This fixes a regression introduced in [50996] where sites that have been opted-out of the block-based widget editor experienced an “Invalid value.” error when adding a new widget to a sidebar in the Customizer.

This was caused by the early return value was changed to `null` from `$value` when set to an empty `array`, resulting in the widget being evaluated as invalid elsewhere.
