Description

This PR improves how we enrich contact data with company info for email previews, example sends, and regular sends from a contact list or detail page.
It ensures {contactfield=companyname} and similar company tokens work reliably, even when there’s no real contact selected.

✨ Change log

• Updated sendExampleAction and previewAction to use enriched contacts.
• Added prepareFakeContactWithPrimaryCompany() to create realistic fake contact+company data for previews.
• Ensured that token replacements include company information for both real and imaginary contacts.

User stories

1. Email Preview
   As a marketing user,
   I want the contact used in email previews to include the primary company information,
   so that I can verify if all tokens, including company tokens, are correctly replaced before sending the email.

2. Example email
   As a marketing user,
   I want the example emails I send to myself (or others) to use an enriched contact that includes primary company details,
   so that I can test if personalization tokens for contacts and their companies are working correctly.

3. Send Email from Contact Listing
   As a marketing user,
   I want to ensure that when sending an email from a contact's listing or detail view, the email uses a contact record enriched with its primary company information,
   so that all contact and company tokens populate correctly in the sent email.
