Tighten report widget selection and dashboard layout rendering - #1556

Report widgets may declare a `permissions` key. `WidgetManager::listReportWidgets()` applies it, the add-widget popup offers only what it returns, and `makeReportWidget()` builds only what it contains -- but `ReportContainer::onAddWidget()` took the class name from the request and constructed it regardless. It now works from that same list, and consults it before the class name is used for anything else, so every name that is not on it gets the same answer. `listReportWidgets()` now applies the permission filter to a copy rather than to its own memo: the widget manager is a singleton for the life of the process, so filtering the memo hid a widget from every later caller in that process, including one acting as a user who does hold the permission. The container renders two of a layout's stored values into attributes of its own, the column count and the sort order, and a layout can be published to every other backend user by a holder of `backend.manage_default_dashboard`. Every sort order the container derives or stores is now an integer, both values are compared and rendered as integers, the remaining values in both container partials and in the toolbar partial they include are escaped, and `onUpdateWidget()` keeps only the properties the container publishes for the widget -- the same set it offers the inspector -- refusing a payload it can make none of those values out of rather than applying it as an empty set, which would replace the widget's configuration with its declared defaults. Typing the container's own two values also keeps a dashboard renderable when a layout stored earlier holds something other than a number in either of them. A report widget's title gets the same treatment, through a new `ReportWidgetBase::getTitle()` that the three core report widget partials use. `trans()` resolves a key naming a translation group to an array rather than a string, which cannot be rendered, so a title of that shape stored in a published layout made every dashboard serving that layout unrenderable -- including the toolbar that would have let it be reset. The configured value is now rendered as written whenever translating it does not produce a string. Behaviour changes: - A report widget class that is not on the list the current user may add is refused by `onAddWidget()`, with the same answer whether it is unregistered, misspelled or permission-restricted. - `onUpdateWidget()` stores only the properties the container publishes for that widget at the time of the request. A widget whose declared property set depends on one of its own values will not have a property stored in the same request that first publishes it; posting the two changes in sequence stores both. - A stored column count or sort order that is not a number is rendered and compared as an integer rather than as written. - A title whose translation key names a group renders as the configured text instead of failing the dashboard. - `onRemoveWidget()` and `onSetWidgetOrders()` are unchanged: both act only on keys already present in the acting user's own stored layout and construct no widget, so neither reaches the permission filter. (The internal note that said all four handlers resolve through `makeReportWidget()` was wrong about these two.) Covered by `Backend\Tests\Widgets\ReportContainerSecurityTest` (38 tests) and two cases added to `Backend\Tests\Controllers\IndexSecurityTest`, including `testTheContainerAndItsToolbarEscapeTheContainerAlias`, `testATitleNamingATranslationGroupStillRendersTheDashboard`, `testTheWidgetListIsNotHiddenFromALaterUserInTheSameProcess` and `testTheStoredWidgetWidthIsAnInteger`. 30 of the 38 fail without the production changes.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughReport-widget operations now validate widget classes and submitted properties, and normalize layout widths and sort orders. Dashboard templates escape rendered attribute values.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A non-string fields input can raise a TypeError instead of the intended refusal.
json_decode() requires a string. If a client posts fields[]=x, Request::input('fields') returns an array. PHP 8.1+ then throws a TypeError before the is_array guard runs, and the handler returns a 500 error instead of 'Invalid widget properties posted.'. The stored configuration does not change, so the impact is limited to the error contract. To fix this, check the input type before decoding.
Proposed fix
- $properties = json_decode(Request::input('fields'), true);
+ $fields = Request::input('fields');
+ $properties = is_string($fields) ? json_decode($fields, true) : null;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
