Update Frontend for Custom Result Index Query and Fix Issues

[kaituo]

Description

This PR finalizes the frontend changes related to PR #1225. The custom result index query now uses an index pattern instead of a single index.

Additionally, this PR addresses an issue where missing custom result indices would appear because the original code checked for the existence of an index name, but now we use it as a prefix. We have updated the logic to perform a prefix search instead of checking for index name equality.

This PR also resolves issue #765 by downgrading the version of jest-canvas-mock.

Testing Done:

• Added unit tests.
• Verified that the custom result index missing callout is not shown.
• Confirmed that the frontend can still display old and new results after a rollover.

In the latest commit, I have made the following changes:

• Rebased Code: Rebased my code from the main branch.
• Alias Check: Updated the alias check to use equality instead of a prefix check. For more details, refer to this discussion.
• Removed ISM Plugin in Custom Index callout: Removed the use of the ISM plugin in the custom index part of the create detector workflow. The min_age and similar parameters are required and cannot be omitted. Even if these parameters are made optional, they default to empty strings, which the backend AnomalyDetector' parse method expects to be integers. So cx cannot to choose ISM to manage their plugin.
  • Before
  - After
• Configuration Review Page: Modified the configuration review page to exclude ISM parameter units when the custom result index is empty for a cleaner appearance.
  • Before:
    
  • After:

Thanks for the change!
There's another place that's also calling search result index - https://github.com/opensearch-project/anomaly-detection-dashboards-plugin/blob/main/public/expressions/helpers.ts#L32 that needs to be updated. I'm working on a MDS related fix on this part, I can update it
