Can't remove the offset between text and bottom border (underline) for Entry

### Description

After visually removing the `Entry` underline by setting `Background` to `null` and setting `Padding` to `0` on all sides, to achieve the effect I want, there is still **extra space** between the text and underline.

Without underline:

With underline:

This clearly comes from the component itself. I did not find any setting that either adjusts the text position or actually removes the underline from being rendered allowing text to be directly placed on top of underline without that extra space between text and underline.

### Steps to Reproduce

1. Create an empty MAUI project.
2. Add a `ContentPage` using a template, and add an `Entry`:

`MainPage.xaml`

```

```

`MainPage.xaml.cs`

```
namespace YourApp;

public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
}
}
```

4. Create a `CustomEntryHandler` for said Entry:

```
#if ANDROID

using Microsoft.Maui.Handlers;
using Microsoft.Maui.Platform;

namespace YourApp;

public class CustomEntryHandler : EntryHandler
{
protected override void ConnectHandler(MauiAppCompatEditText platformView)
{
base.ConnectHandler(platformView);
platformView.SetPadding(0, 0, 0, 0);
platformView.ShowSoftInputOnFocus = false;
if (OperatingSystem.IsAndroidVersionAtLeast(29))
{
// Or darker color if on lighter background
platformView.TextCursorDrawable?.SetTint(Colors.Lavender.ToInt());
}
}
}

#endif
```

5. Wire it up to `Entry` in `MauiProgram.cs`:
```
using Microsoft.Maui;
using Microsoft.Maui.Hosting;

namespace YourApp;

public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();

builder
.UseMauiApp()
.ConfigureMauiHandlers(handlers =>
{
handlers.AddHandler();
});

return builder.Build();
}
}
```
6. Expected behavior: no padding between text and underline.
7. Actual behavior: there is padding between text and underline.

Start with the Android Entry handler and the CustomEntryHandler shown in the issue, using MainPage.xaml and MauiProgram.cs to reproduce the behavior. Compare the native EditText underline and padding behavior when the handler sets all padding to zero. Done means the Android Entry text sits directly against the underline without the unwanted gap, with coverage for the reported setup.
