## Why are the changes needed?

This PR provides clear documentation on how Flyte resolves console URL templates, starting from Helm chart configurations, through FlyteAdmin, and finally to runtime URL construction for UI links. This addresses a common question about Flyte's internal workings for UI link generation.

## What changes were proposed in this pull request?

This PR introduces a new markdown document, `flyte-console-url-resolution.md`, which comprehensively explains the end-to-end process of how Flyte resolves console URLs. The document details:
*   Helm chart configuration (`values.yaml`, `configmap.yaml`)
*   Configuration loading in FlyteAdmin (`application_configuration.go`)
*   Embedding of the console URL into the workflow CRD (`k8s_executor.go`, `workflow.go`)
*   Runtime construction of task-specific URLs (`k8s_resource_adds.go`)
*   The final URL template format.
It also lists key files and their roles in this resolution pipeline.

## How was this patch tested?

This is a documentation-only change. The content was generated through a detailed analysis of the Flyte codebase to accurately describe the console URL resolution process. No code changes were made, and therefore no new tests were added or existing tests run.
