[BUG] ISM plugin doesn't recognize `convert_index_to_remote` action type (blank policy details page)

[cmklem]

What is the bug?
When an ISM policy contains the convert_index_to_remote action (introduced in OpenSearch 3.5.0), attempting to view that policy in the Dashboards plugin results in a blank page. The error in browser dev tools:

Error: Action type [convert_index_to_remote] not supported

The policy and API behave fine, but the UI does not support the new action type.

How can one reproduce the bug?

1. Create an ISM policy with the convert_index_to_remote action.
2. Dashboards > Index Management > State management policies (policies are listed)
3. Click the policy just created.
4. A page loads but, apart from the Dashboards header, there is no content. If the policy does not contain convert_index_to_remote, it loads as expected.

What is the expected behavior?
The page should load successfully and display policy details.

What is your host/environment?

• OS: (e.g.) Ubuntu 24.04
• OpenSearch: 3.6.0 (deb)
• OpenSearch Dashboards: 3.6.0 (deb)
• Plugins: ISM, repository-s3

Do you have any screenshots?

Do you have any additional context?

• convert_index_to_remote was apparently introduced in OpenSearch 3.5.0 (release note).
• The underlying ISM REST API returns the policy correctly, but Dashboards throws an error and fails to render the UI for that action type.
• Possibly related (but distinct): [BUG] Blank page when trying to list sm policies when one of them does not have creation field #1405

A fix could consist of registering a new action type convert_index_to_remote in the Dashboards plugin.

@vikasvb90 @soosinha Can you help find a maintainer to take a look at this issue?

This #1373 will solve the problem. Looking at the labels - it's target for v3.8.0
