Fix BoLA A19 sample attribution

[iskandr]

Summary

• restore 2824TP's measured A19 genotype to BoLA-2*016:01 BoLA-6*014:02
• preserve the paper's three BoLA-6*014:01 peptide predictions as exact, predicted observation restrictions
• add source-backed peptide-to-2824TP attribution and allow resolved rows to carry a curated sample label without rewriting their restriction
• document and regression-test the separation between sample typing, row restriction, and restriction evidence
• bump Hitlist to 1.57.1

Primary-source resolution

Results 3.2 of Connelley/Sheldrake 2022 and the independent Vasoya et al. A19 definition identify A19 as BoLA-2*016:01 plus BoLA-6*014:02. However, Connelley Table 3 and Supplementary Data 2.1 assign the three retained peptides to BoLA-6*014:01 by prediction. The supplement contains 23 *014:01 predictions, all in 2824TP runs, and no *014:02 predictions.

IEDB faithfully retained the paper's three final-table predictions, so this is not an upstream IEDB ingestion defect and no upstream issue was filed. The published source-level discrepancy remains explicit in the curation note and issue discussion; this PR represents both facts without declaring the alleles equivalent.

Verification

• ./format.sh
• ./lint.sh
• ./test.sh — 1,190 passed, one expected warning
• pytest -q tests/test_build_smoke.py — 2 passed
• real scan of the 7.77 GB IEDB export — exactly the three expected PMID 36423003 rows retained Bota-6*014:01, exact, and predicted, each attributed to 2824TP
• sample_ploidy_audit() — clean corpus-wide

Closes #414
