chore: bump starter version to 20260409 across Docker Compose examples (#35273)

## Description

Updates `CUSTOM_STARTER_URL` across all Docker Compose example
configurations from version `20260331` to `20260409`, keeping them
aligned with the latest UVE changes.

- Updated 10 Docker Compose files under
`docker/docker-compose-examples/`
- Affected configurations: `single-node`, `single-node-demo-site`,
`single-node-debug-mode`, `cluster-mode`, `push-publish`,
`with-opensearch-dashboard`, `with-redis`, `with-redis-session`
- Most entries are commented out (used for local testing); only
`single-node-demo-site` has the URL active by default

## Linked Issues

Closes #35211

## Testing

No functional changes — this only updates the starter bundle version
referenced in Docker Compose example files. Manual verification: spin up
`single-node-demo-site` and confirm it pulls the `20260409` starter.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Only updates example Docker Compose configuration values, mainly
commented-out `CUSTOM_STARTER_URL`s, with no application code changes.
Risk is limited to users relying on these examples pulling a different
starter bundle.
> 
> **Overview**
> Updates Docker Compose example configs to reference the `20260409`
starter bundle instead of `20260331` via `CUSTOM_STARTER_URL`.
> 
> Most changes are commented example settings;
`single-node-demo-site/docker-compose.yml` updates the active
`CUSTOM_STARTER_URL` used by default.
