Add Configurable Dashboard Route

[georgidhristov]

Description

DebugProbe currently exposes its dashboard UI through the default /debug route.

While the default route works well for most applications, users do not currently have a simple way to customize the dashboard endpoint when route conflicts, organizational standards, or security requirements exist.

DebugProbe should provide a configuration option that allows users to customize the dashboard route while preserving the existing default behavior.

Current Behavior

The dashboard UI is always available at:

/debug

There is currently no dedicated option to change the dashboard route.

Expected Behavior

Users should be able to configure a custom dashboard route through DebugProbe options.

The default route should remain /debug to preserve existing behavior.

Example:

builder.Services.AddDebugProbe(options =>
{
    options.RoutePrefix = "/debugdashboard";
});

Result

After this change:

• users can customize the dashboard route to match their application requirements
• route conflicts with existing endpoints can be avoided
• DebugProbe becomes more flexible for different deployment environments
• existing applications continue to work without any changes because /debug remains the default route
