…tools flyout (elastic#261876)

> [!NOTE]
> Most of the changes in this PR are actually just files moved.

## Summary

This PR removes the dependency on `useExpandableFlyoutApi` from the code
in the `flyout_v2` folder. This should not have been there but it
slipped through the cracks. Currently, the `RelatedAttacks` logic in our
`Correlations` flyout would not work and the behavior would be broken,
trying to open a left expandable flyout next to a new flyout system
tools flyout.

Additionally, I took the opportunity to do the following cleanup:
- move a few hooks and functions to the `correlations` folder, that had
been left behind in the old `flyout` folder
- slightly changed a UI logic to always show the related attacks, even
if there are none. This was missed during code review, and is now more
in line with the other correlations items, both in the overview and in
the tools flyout

## How to test

To see the new (emtpy) flyout in Security Solution, add this to your
`kibana.dev.yml` file:
```xpack.securitySolution.enableExperimental: [ 'newFlyoutSystemEnabled' ]```

Too see the new (emtpy) flyout in Discover, add this to your `kibana.dev.yml` file:
```discover.experimental.enabledProfiles: [
'enhanced-security-document-profile' ]```

    [Search] Onboarding agent api snippet context (elastic#261405)

    The onboarding agent in [the skills
    repo](https://github.com/elastic/agent-skills-sandbox/tree/main/skills/elasticsearch/elasticsearch-onboarding)
    is better suited for guiding a user through end-to-end solution
    development. Agent Builder is limited with its ability to set up
    resources for a user and deploy an application.

    For this reason, the search onboarding agent should be aware of this
    limitation in how it onboards a user.

    This change instructs the agent to lean on API snippets the user can
    leverage to create resources while still in Kibana, and help guide them
    further if they wish to continue in their IDE. As such, we remove some
    client/language specific code and language in this change.

    [One Workflow] New Cases action menu group under Kibana (elastic#261964)

    ## Summary

    Part of: elastic/security-team#15982.
    (Resolves requirement `#4`)

    This change introduces a dedicated **`StepCategory.KibanaCases`**
    (`kibana.cases`) so Cases workflow steps are grouped under **Kibana →
    Cases** in the workflow actions menu instead of sitting in the flat
    Kibana list.

    **Actions menu (`workflows_management`)**

    - Builds a **Cases** subgroup (`id: kibana.cases`) under the Kibana
    group via **`nestedGroups`**, then merges any non-empty nested group
    into the parent’s **`options`** so the UI stays a normal tree of groups.
    - Assigns **`pathIds`** on every group (full path from the root) so
    choosing a nested group from **search** opens the correct depth (Kibana
    → Cases → …) instead of only appending the last segment.
    - **`ActionsMenu`** uses `selectedOption.pathIds ?? [...currentPath,
    id]` when entering a group.

    **Shared spec**

    - Adds **`StepCategory.KibanaCases`** in `@kbn/kbn-workflows` so step
    definitions and UI routing can target the Cases bucket explicitly.

    **Cases plugin**

    - Updates all Cases **common workflow step** definitions to use
    **`StepCategory.KibanaCases`** instead of **`StepCategory.Kibana`**.

    **Agent builder**

    - **`get_step_definitions_tool`**: maps connector types **`cases.*`** →
    **`KibanaCases`** and keeps **`kibana.*`** → **`Kibana`**.

    **Tests**

    - Extends **`get_action_options.test.ts`** for nested Cases, empty Cases
    group hidden, **`pathIds`**, and ordering expectations.

commit 9b58980

    Fix cross-project search for index threshold chart preview (elastic#261593)

    ### Summary

    Index threshold rule UI could list indices using the CPS project scope
    (via `POST .../data/_indices` and `project_routing`), but the chart
    preview called `POST
    .../internal/triggers_actions_ui/data/_time_series_query` without
    `project_routing`. The server-side Elasticsearch client then defaulted
    to origin-only routing, so preview did not match the picker.

    This change threads optional `**project_routing**` through the
    time-series query API and the threshold visualization so preview uses
    the same CPS scope as index selection.

    ### Changes

    - **`triggers_actions_ui`**: Extend `TimeSeriesQuerySchema` with
    optional `project_routing`; pass it from `timeSeriesQuery` into
    **`search`** and **`fieldCaps`** (including `fetchDataViewBase` for KQL
    filter typing).
    - **`stack_alerts`**: `getThresholdRuleVisualizationData` accepts
    optional `projectRouting` and sends **`project_routing`** in the JSON
    body; **`ThresholdVisualization`** reads
    `cps.cpsManager.getProjectRouting()` and passes it through, with a
    refetch when routing changes.
    - **Tests**: Schema validation for `project_routing`; unit tests for API
    body shape; visualization tests for CPS vs no CPS; `time_series_query`
    tests assert ES calls include `project_routing` when set.

    ### How to test

    1. On a CPS-enabled serverless deployment, set the project picker to
    search linked projects (`_alias:*` or equivalent).
    2. Create or edit an index threshold rule targeting data outside the
    origin project.
    3. Confirm the preview chart loads data consistent with the selected
    indices (not empty or scoped only to the origin project).

    fix(search): add page context awareness to agent builder

    Agent Builder knows which Kibana page the user is on. This adds a Page
    Context section that adapts the conversation based on the current page
    (Index Management, Dev Tools, Connectors, File Data Visualizer, etc.).

    When the user is already on Dev Tools, skip conceptual setup and jump
    straight to generating the API snippets they need.
