Fix null handling for deliverables in create_template_for_owner (#51)

The previous code used `.unwrap_or_default()` which could produce
`Some(Value::Null)` if JSON serialization failed, leading to
inconsistent handling when the database returned NULL and sqlx
attempted to decode with the `#[sqlx(json)]` attribute on an Option type.

Changed to use `.ok()` which properly returns `None` when serialization
fails, ensuring consistent NULL handling between the application and
database layer.

Fixes: "Failed to create template: error occurred while decoding column
'deliverables': unexpected null; try decoding as an Option"
