misaligned message items in message list

[mildrette]

In the message list screen, messages sent via Bluesky (and other platforms
without a subject line) have misaligned layout, the platform icon sits
higher than expected while the message text sits lower.

• Expected Behavior

All message list items should be vertically aligned consistently,
regardless of whether they have a title/subject or just a body text.

Steps to Reproduce

1. Send a message via Bluesky
2. Go to the Messages screen
3. Compare the Bluesky item alignment with a Gmail item
