WhatsApp template variables like `{{contact.first_name}}` previously
resolved to an empty string whenever a contact or agent had a
single-word name (e.g. "Petterson"). Because the variable came back
blank, WhatsApp template sends would either fail validation or get stuck
indefinitely in the "Sending" state. With this fix, `first_name` falls
back to the full single-word name, so templates render correctly for
everyone regardless of how many words their name has.
## Closes
- Fixes#13222
## How to reproduce
1. Create a contact with a single-word name (e.g. `Petterson`).
2. Configure a WhatsApp template action that uses
`{{contact.first_name}}`.
3. Send the template message.
4. **Before:** the variable resolves to an empty string and the message
fails / stays in "Sending".
**After:** the variable resolves to `Petterson` and the message sends.
## What changed
- Removed the "name must have 2+ words" guard from `first_name` in
`ContactDrop` and `UserDrop`, so a single-word name is returned (still
capitalized).
- Capitalization behavior introduced in #6758 is preserved; only the
single-word edge case changes.
- `last_name` still returns `nil` for single-word names, which is the
expected behavior.
- Added specs covering single-word names for both `ContactDrop` and
`UserDrop`.

# Pull Request Template
## Description
This PR fixes an issue where agent variables like
`{{agent.name}}`,`{{agent.first_name}}`, `{{agent.last_name}}`, and
`{{agent.email}}` were not rendering in automation messages.
In automation, these either showed blank or returned `Liquid error:
internal`, while the same variables worked fine in macros.
**Cause**
Automation messages are created without a sender, so agent data was
missing during variable rendering. This also caused errors in name
handling, and `email` was not defined at all.
**Solution**
* Handle missing agent data safely to avoid errors
* Add support for `{{agent.email}}`
* Fallback to conversation assignee when sender is not present
