fix(HttpClient): take Uri by value in request() to prevent dangling reference

The coroutine suspends at co_await, so a const-ref to a temporary Uri
would dangle. Take by value like the download() overloads already do.

-# Telemetry Events
-
-PowerToys collects limited telemetry to understand feature usage, reliability, and product quality. When adding a new telemetry event, follow the steps below to ensure the event is properly declared, documented, and available after release.
-
-**⚠️ Important**: Telemetry must never include personal information, file paths, or user‑generated content.
-
-## Developer Effort Overview (What to Expect)
-
-Adding a telemetry event is a **multi-step process** that typically spans several areas of the codebase and documentation.
-
-At a high level, developers should expect to:
-
-1. Within one PR:
-    1. Add a new telemetry event(s) to module
-    1. Add the new event(s) DATA_AND_PRIVACY.md
-1. Reach out to @carlos-zamora or @chatasweetie so internal scripts can process new event(s)
-
-### Privacy Guidelines
-
-**NEVER** log:
-
-- User data (text, files, emails, etc.)
-- File paths or filenames
-- Personal information
-- Sensitive system information
-- Anything that could identify a specific user
-
-DO log:
-
-- Feature usage (which features, how often)
-- Success/failure status
-- Timing/performance metrics
-- Error types (not error messages with user data)
-- Aggregate counts
-
-### Event Naming Convention
-
-Follow this pattern: `UtilityName_EventDescription`
-
-Examples:
-
-- `ColorPicker_Session`
-- `FancyZones_LayoutApplied`
-- `PowerRename_Rename`
-- `AdvancedPaste_FormatClicked`
-- `CmdPal_ExtensionInvoked`
-
-## Adding Telemetry Events to PowerToys
-
-PowerToys uses ETW (Event Tracing for Windows) for telemetry in both C++ and C# modules. The telemetry system is:
-
-- Opt-in by default (disabled since v0.86)
-- Privacy-focused - never logs personal info, file paths, or user-generated content
-- Controlled by registry - HKEY_CURRENT_USER\Software\Classes\PowerToys\AllowDataDiagnostics
-
-### C++ Telemetry Implementation
-
-**Core Components**
-
-| File  | Purpose |
-| ------------- |:-------------:|
-| [ProjectTelemetry.h](../../src/common/Telemetry/ProjectTelemetry.h)    | Declares the global ETW provider g_hProvider     |
-| [TraceBase.h](../../src/common/Telemetry/TraceBase.h)      | Base class with RegisterProvider(), UnregisterProvider(), and IsDataDiagnosticsEnabled() check     |
-| [TraceLoggingDefines.h](../../src/common/Telemetry/TraceLoggingDefines.h)      | Privacy tags and telemetry option group macros
-
-
-#### Pattern for C++ Modules
-
-1. Create a `Trace` class inheriting from `telemetry::TraceBase` (src/common/Telemetry/TraceBase.h):
-
-    ```c
-    // trace.h
-    #pragma once
-    #include <common/Telemetry/TraceBase.h>
-    
-    class Trace : public telemetry::TraceBase
-    {
-    public:
-        static void MyEvent(/* parameters */);
-    };
-    ```
-
-2. Implement events using `TraceLoggingWriteWrapper`:
-
-    ```cpp
-    // trace.cpp
-    #include "trace.h"
-    #include <common/Telemetry/TraceBase.h>
-    
-    TRACELOGGING_DEFINE_PROVIDER(
-        g_hProvider,
-        "Microsoft.PowerToys",
-        (0x38e8889b, 0x9731, 0x53f5, 0xe9, 0x01, 0xe8, 0xa7, 0xc1, 0x75, 0x30, 0x74),
-        TraceLoggingOptionProjectTelemetry());
-    
-    void Trace::MyEvent(bool enabled)
-    {
-        TraceLoggingWriteWrapper(
-            g_hProvider,
-            "ModuleName_EventName",           // Event name
-            TraceLoggingBoolean(enabled, "Enabled"),  // Event data
-            ProjectTelemetryPrivacyDataTag(ProjectTelemetryTag_ProductAndServicePerformance),
-            TraceLoggingBoolean(TRUE, "UTCReplace_AppSessionGuid"),
-            TraceLoggingKeyword(PROJECT_KEYWORD_MEASURE));
-    }
-    ```
-
-**Key C++ Telemetry Macros**
-
-| Macro  | Purpose |
-| ------------- |:-------------:|
-| `TraceLoggingWriteWrapper` [CustomAction.cpp](../../installer/PowerToysSetupCustomActionsVNext/CustomAction.cpp)     | Wraps `TraceLoggingWrite` with `IsDataDiagnosticsEnabled()` check     |
-| `ProjectTelemetryPrivacyDataTag(tag)` [TraceLoggingDefines.h](../../src/common/Telemetry/TraceLoggingDefines.h)     | Sets privacy classification |
-
-### C# Telemetry Implementation
-
-**Core Components**
-
-| File  | Purpose |
-| ------------- |:-------------:|
-| [PowerToysTelemetry.cs](../../src/common/ManagedTelemetry/Telemetry/PowerToysTelemetry.cs)    | Singleton `Log` instance with `WriteEvent<T>()` method     |
-| [EventBase.cs](../../src/common/ManagedTelemetry/Telemetry/Events/EventBase.cs)      | Base class for all events (provides `EventName`, `Version`)     |
-| [IEvent.cs](../../src/common/ManagedTelemetry/Telemetry/Events/IEvent.cs)     | Interface requiring `PartA_PrivTags` property     |
-| [TelemetryBase.cs](../../src/common/Telemetry/TelemetryBase.cs)     | 	Inherits from `EventSource`, defines ETW constants     |
-| [DataDiagnosticsSettings.cs](../../src/common/ManagedTelemetry/Telemetry/DataDiagnosticsSettings.cs)     | Registry-based enable/disable check 
-
-#### Pattern for C# Modules
-
-1. Create an event class inheriting from `EventBase` and implementing `IEvent`:
-
-    ```csharp
-    using System.Diagnostics.CodeAnalysis;
-    using System.Diagnostics.Tracing;
-    using Microsoft.PowerToys.Telemetry;
-    using Microsoft.PowerToys.Telemetry.Events;
-    
-    namespace MyModule.Telemetry
-    {
-        [EventData]
-        [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicProperties)]
-        public class MyModuleEvent : EventBase, IEvent
-        {
-            // Event properties (logged as telemetry data)
-            public string SomeProperty { get; set; }
-            public int SomeValue { get; set; }
-    
-            // Required: Privacy tag
-            public PartA_PrivTags PartA_PrivTags => PartA_PrivTags.ProductAndServiceUsage;
-    
-            // Optional: Set EventName in constructor (defaults to class name)
-            public MyModuleEvent(string prop, int val)
-            {
-                EventName = "MyModule_EventName";
-                SomeProperty = prop;
-                SomeValue = val;
-            }
-        }
-    }
-    ```
-
-2. Log the event:
-
-```csharp
-PowerToysTelemetry.Log.WriteEvent(new MyModuleEvent("value", 42));
-```
-
-**Privacy Tags (C#)**
-
-| Tag  | Use Case |
-| ------------- |:-------------:|
-| `PartA_PrivTags.ProductAndServiceUsage`  [TelemetryBase.cs](../../src/common/Telemetry/TelemetryBase.cs)     | Feature usage events
-| `PartA_PrivTags.ProductAndServicePerformance` [TelemetryBase.cs](../../src/common/Telemetry/TelemetryBase.cs)     | Performance/timing events
-  
-### Update DATA_AND_PRIVACY.md file
-
-Add your new event(s) to [DATA_AND_PRIVACY.md](../../DATA_AND_PRIVACY.md).
-
-## Launch Product Version Containing the new events
-
-Events do not become active until they ship in a released PowerToys version. After your PRs are merged:
-
-- The event will begin firing once users install the version that includes it
-- In order for PowerToys to process these events, you must complete the next section
-
-## Next Steps
-
-Reach out to @carlos-zamora or @chatasweetie so internal scripts can process new event(s).
-
-## Summary
-
-Required steps:
-
-1. In one PR:
-    - Add the event(s) in code
-    - Document event(s) in DATA_AND_PRIVACY.md
-1. Ship the change in a PowerToys release
-1. Reach out for next steps
