Document scripting limit defaults and config

Update low-code scripting API docs to clarify and expose configurable limits. Adds a new Configuration section with an example Configure<AbpLowCodeScriptingOptions> showing script and query limits (null = no limit). Changes many default values in Sandbox Constraints and Query Security Limits from concrete numbers to "No limit", removes per-group/item rows (MaxItemsPerGroup, MaxTotalGroupedItems) and consolidates group limits to MaxGroupCount. Notes that all limits default to null and should be set according to security requirements and expected workload.

+## Configuration
+
+You can configure scripting limits using `AbpLowCodeScriptingOptions` in your module's `ConfigureServices` method:
+
+```csharp
+Configure<AbpLowCodeScriptingOptions>(options =>
+{
+    // Script execution limits (null = no limit)
+    options.Script.Timeout = TimeSpan.FromMinutes(1);
+    options.Script.MaxStatements = 100_000;
+    options.Script.MaxMemoryBytes = 512 * 1024 * 1024; // 512 MB
+    options.Script.MaxRecursionDepth = 500;
+
+    // Query API limits (null = no limit)
+    options.Query.MaxLimit = 10_000;
+    options.Query.DefaultLimit = 1000;
+    options.Query.MaxExpressionNodes = 200;
+    options.Query.MaxExpressionDepth = 20;
+    options.Query.MaxArraySize = 500;
+    options.Query.MaxGroupCount = 500;
+});
+```
+
+All limits default to `null` (no limit). Configure them based on your security requirements and expected workload.
