<issue_title>[Blazor] Accept the blazor.web.js startup options format in blazor.{server|webassembly}.js</issue_title>
<issue_description>## Problem

When a Blazor app uses blazor.web.js, the options object passed to Blazor.start() has the following format:

Blazor.start({
  ssr: { /* ... */ },
  circuit: { /* ... */ },
  webAssembly: { /* ... */ },
});

However, when using blazor.server.js or blazor.webassembly.js, runtime-specific options are specified as top-level properties on the options object. So, for example, if you're using blazor.webassembly.js and you attempt to customize the loading of boot resources like this:

Blazor.start({
  webAssembly: {
    loadBootResource: function (/* ... */) {
      // ...
    },
  },
});

...then it will just silently "not work". This could create a pit of failure for customers who see examples in docs using the blazor.web.js options format but are writing a Blazor WebAssembly standalone app, for example.

Solution

We should update blazor.webassembly.js and blazor.server.js to accept the options format used by blazor.web.js.
Include end-to-end test that will assert that options are passed correctly

<agent_instructions>Follow the instructions in src/Components/Agents.md

You MUST follow this workflow when implementing new features or fixing bugs in the Components area.

• Add the workflow to your todos and follow it strictly.

• Create a sample scenario.
• If working on a bug, use playwright to reproduce the behavior/problem first.
• You MUST have reproduced the problem before attempting to fix it.
• Research the problem area using the microsoft docs, existing code, git history, and logging on the sample project.
• Implement the fix or feature in the sample project first.
• Test the fix or feature interactively using Playwright.
• Once the fix or feature is validated in the sample, implement E2E tests for it.
  • When you create an E2E test. First execute it interactively with Playwright.
  • If an E2E test is failing, debug it by running the test server manually and navigating to the scenario in a browser.
• Only after the E2E tests are passing, remove the sample code you added in the Samples projects.

In this case, for the E2E tests you can probably modify one of the App.razor files in the testassets that use blazor.web.js and take parameters to use the new format. Make sure that there is at least one file that uses the new format and one that uses the old format.</agent_instructions>
