LCFS - Investigate missing “fuel code” option in carbon intensity determination (2019–2023) Test

**Describe the Bug**
In historical compliance reports (2019–2023), the “fuel code” option is missing from the carbon intensity determination pathway for petroleum fuels.

**Expected Behaviour**
Where applicable under the Act, the system should include a “fuel code” option as part of determining carbon intensity for petroleum fuels in 2019–2023 reports.

**Actual Behaviour**
The “fuel code” option is not available in the carbon intensity selection, limiting users to incomplete or incorrect determination pathways.

**Implications**
- Incomplete or incorrect carbon intensity determination under the Act
- Inconsistency with expected reporting logic and fuel code structure
- Risk of non-compliant reporting outcomes
- Increased manual intervention by analysts

**Steps to Reproduce**
1. Open a 2019–2023 compliance report
2. Enter petroleum fuel data (gasoline or diesel)
3. Navigate to carbon intensity / section selection
4. Observe absence of “fuel code” option

**Acceptance Criteria**
- “Fuel code” option appears where required for 2019–2023 reporting
- Availability aligns with Act-based carbon intensity determination rules
- Logic is consistent with fuel code configuration and lookup tables
- Behaviour is validated against expected pathways defined in card #867

**Additional context**
- Related to card #867 (section selection restriction for petroleum fuels)
- Likely caused by lookup table or mapping issue affecting historical reporting years
- Identified during testing session review of carbon intensity determination logic

Reproduce the missing option in a 2019–2023 compliance report using petroleum fuel data, then compare the carbon-intensity determination path with the expected pathways in card #867. Inspect the fuel-code configuration or lookup tables and the historical reporting-year mapping. Done means the option appears where required and its availability matches the Act-based rules and expected pathways.
