Added support for prompting for parameter values in run mode#10235
Conversation
- Handle prompting for parameters once they have all been processed. This also handles re-prompting until they have all been processed. - Introduced MissingParameterValueException to detect when parameters are have a missing value. - Moved all parameter processing logic into ParameterProcessor

Pull Request Overview
This PR centralizes parameter handling into a new ParameterProcessor, introduces MissingParameterValueException for missing parameter values, and updates existing builders and orchestrator to use this new flow.
- Tests now expect
MissingParameterValueExceptioninstead ofDistributedApplicationException. - A
ParameterProcessorclass encapsulates init/handling logic forParameterResource. - The orchestrator and builder are updated to register and invoke the new processor upfront.

- [nitpick] It would be beneficial to add a unit test in
ApplicationOrchestratorTeststo verify thatParameterProcessor.InitializeParametersAsyncis invoked and correctly initializes parameters during orchestration startup.
await _parameterProcessor.InitializeParametersAsync(_model.Resources.OfType<ParameterResource>()).ConfigureAwait(false);

[nitpick] This test class is over 350 lines long, covering multiple scenarios. Consider splitting it into smaller, focused test classes (e.g., initialization tests vs. unresolved-parameter handling tests) to improve readability and maintainability.
