fix: hide template selector after shared workflow accept (#9913)

## Summary

Hide the template selector when a first-time cloud user accepts a shared
workflow from a share link, so the shared workflow opens without the
onboarding template dialog lingering.

## Changes

- **What**: Added shared-workflow loader behavior to close the global
template selector on accept actions (`copy-and-open` and `open-only`)
while keeping cancel behavior unchanged.
- **What**: Added targeted unit tests covering hide-on-accept and
no-hide-on-cancel behavior in the shared workflow URL loader.

## Review Focus

Confirm that share-link accept paths now dismiss the template selector
and that cancel still leaves it available.
