Benefits Denial/fair.py's National-Origin proxy comment says "4.8%" where the real, printed gap is 4.40%

Where: Benefits Denial/fair.py, the proxy-removal commentary block:

native.country → protected (national origin). Foreign-born
                 applicants are flagged ineligible at 4.8%
                 lower rates in the biased model - not
                 because of economic differences, but because
                 the country variable encodes labour market
                 discrimination into the prediction.

The gap: the real, printed gap from running the biased model is 4.40%, not 4.8%. Every other place this number appears in the repo agrees on 4.40%:

$ python3 "Benefits Denial/unfair.py" | grep -i origin
── Ineligibility Flag Rate by National Origin ───────────
  US-born            : 20.20% flagged ineligible
  Foreign-born       : 15.81% flagged ineligible
  Fairness Gap (Origin): 4.40%

$ grep -n "4.40\|4.8" "Benefits Denial/README.md" README.md
Benefits Denial/README.md:31:| Origin | 4.40% | 0.52% | 88% |
README.md:78:| ... | Origin: 4.40% → 0.52% | **88%** |
README.md:584:| **Fairness Gap (Origin)** | **4.40%** |
README.md:614:| Origin | 4.40% | 0.52% | **88%** |

Only fair.py's own inline comment is wrong, hardcoded at 4.8%.

Fix direction: change "4.8%" to "4.40%" (or "4.4 percentage points") in Benefits Denial/fair.py's comment block.

Open Benefits Denial/fair.py and locate the proxy-removal commentary block mentioning the national-origin gap. Change the incorrect 4.8% figure to 4.40% or 4.4 percentage points, then verify the comment matches the printed result and the other repository references.
