feat(intel): add option to disable AI integration entirely

Previously, the Helm chart required either 'bundled' or 'external' AI mode to be configured, making it
mandatory to include AI integration. This commit introduces a new flag `ai.enabled` to allow disabling
AI features entirely, enabling Intel to be deployed without any AI-related containers or resources.
