Add Wazuh changes (styles and images)

[AlexRuiz7]

Description

The following list of changes have been applied:

• Changes in CSS.
• Logos and icons replacements.
• Replacement of some texts (OpenSearch with Wazuh, for example).
• Changes in the properties of some fonts.
• Replace default values for some platform's settings, as applicationTitle and useExpandedHeader.
• Replace Node options (Unhandled promise error when unable to reach Wazuh API wazuh-dashboard-plugins#3887).
• Replacement of help links with Wazuh's (titles and URLs).
• Disabled the Overview plugin.
• Manage the attempts of installation of the Wazuh plugin (needs further work, but will be done in an individual issue).

List of changes that could not be applied and reason:

• Replace redirections to /home with /app/wazuh. Reason: the Wazuh plugin is not installed by default, This redirection leads to a 404: app not found view. We need to find a better way to do this change.
  To be done in Replace redirection to /home with /app/wazuh #17 as part of Create default config files for Wazuh #26
• Changes to the documentation links and replacement of the OSD version with the Wazuh version. Reason: the version field in the package.json file cannot be changed, as it must match the version of the OpenSearch Indexer. A new field must be added to store the Wazuh version, and new code must be created to read this field during and use it during runtime. Will be done in a separate issue.
  Done in Replace documentation links with Wazuh's #18
• Remove "New to OpenSearch Dashboards" message with link to OpenSearch Dashboards sample data in Dashboard plugin. Reason: this component has several entry points and collateral effects that we need to study. We'll probably need to disable the route to this view and remove all links to it. Some other views might be affected. We'll perform this change in a separate issue.
  Done in Disable the addition of sample data #19

We had to revert the changes on the useExpandedHeader due to Cypress tests not passing. The Cypress test suite looks for the data-test-subject="homeIcon", which is set in the HomeIcon component depending on the value of the useExpandedHeader for some reason.

wazuh-dashboard/src/core/public/chrome/ui/header/home_icon.tsx

Line 37 in 6993cbc

const testSubj = customMark ? 'customMark' : useExpandedHeader ? 'homeIcon' : 'defaultMark';

If the tests pass reverting this change, we'll set this setting to false using the configuration file instead of replacing its default value in the code.

I think this is causing an inconsistent and unexpected behavior while using the dark mode. Needs to be checked.
