[FEATURE] stg_netsuite2_transactions.status does not provide "display" status

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the issue

The current package setup returns 'A', 'B', 'C', etc as transactions status (differently from NS1).
NS2 provides a dedicated function to calculate the display status: https://timdietrich.me/blog/netsuite-suiteql-transaction-statuses/

### Relevant error log or model output

_No response_

### Expected behavior

The "display" status should be 'Fully Billed', 'Open', etc

### dbt Project configurations

basic config

### Package versions

0.7.1

### What database are you using dbt with?

snowflake

### dbt Version

1.3.2

### Additional Context

Solution 1: package should foresee the join with stg_netsuite2__transactionstatus on status and type

```
FROM {{ ref('stg_netsuite2__transactions') }} AS transactions
INNER JOIN {{ ref('stg_transaction_status') }} AS status_map
ON transactions.status = status_map.id
AND transactions.transaction_type = status_map.trantype
```

Solution 2: adding the conversion in the _tmp model

Solution 3: a macro to get the value from the transaction status and type:

```
{% macro get_status_display_value(tr_status, tr_type) %}
SELECT name
FROM {{ source('netsuite2', 'transactionstatus') }}
WHERE id = {{ tr_status }}
AND trantype = {{ tr_type }}
{% endmacro %}
```

### Are you willing to open a PR to help address this issue?

- [X] Yes.
- [ ] Yes, but I will need assistance and will schedule time during our [office hours](https://calendly.com/fivetran-solutions-team/fivetran-solutions-team-office-hours) for guidance
- [ ] No.

Start by inspecting the stg_netsuite2__transactions model and the stg_transaction_status or transactionstatus source mentioned in the issue. Compare the proposed join, temporary-model conversion, and macro approaches, then ensure transaction status output contains display values such as “Fully Billed” and “Open” for the relevant status and transaction type combinations.
