Introduce a set of JSON Schema definitions to support dashboards and visualizations (aggregation, chart, chart-type, descriptor, filter, group, list, number, position, user-filter, visualization, visualization-type). Update page-descriptor.schema.json to include a dashboard property and a conditional requirement when page type is "dashboard", and extend page-type.schema.json enum to include "dashboard". These changes add schema-level validation for dashboard configuration, visualizations (number/chart/list), positioning, and filters.
Add schema definitions for forms (form-descriptor, form-field-descriptor, form-field-type, form-layout-descriptor, form-rule-descriptor) to describe named forms, fields, layouts and conditional rules. Update page-type to include a new "form" page type and extend page-descriptor with form-related properties (formName, createFormName, editFormName, createFormDisplay, editFormDisplay) and conditional validation (require formName for type 'form', keep kanban's required groupByProperty). Extend model.schema.json to include a top-level "forms" array referencing the new form definitions.
Introduce page-type and page-descriptor JSON Schemas to describe UI pages (type enum: dataGrid, kanban, calendar). The PageDescriptor defines name, title, icon, type, entityName, order and a groupByProperty that is conditionally required when type is kanban. Update model.schema.json to add a pages array referencing the new page-descriptor schema so pages can be declared in the model.
Update AI Management docs to describe configurable workspace data source upload options. Adds notes that allowed file extensions and max file size are configurable (default 10 MB), and that deleting a data source removes its embeddings, chunks, and blob. Introduces a new "Configuring Data Source Upload Options" section with a WorkspaceDataSourceOptions example (AllowedFileExtensions, MaxFileSize, ContentTypeMap), lists available properties and helper methods (GetMaxFileSizeDisplay, GetAllowedExtensionsDisplay, GetAcceptAttribute), and a note about registering content extractors for new file types. Also documents the WorkspaceDataSourceManager repository responsibility for full cleanup.
