Final QA pass: verify flagged magnitudes, fix clipped tables, refresh README

- Verified Black (1999) headline against QJE abstract: corrected 2% to
  2.5% per 5% test-score increase; verified Campbell et al. (2011) 27%
  foreclosure discount (text unchanged).
- Fixed two pre-existing table-clipping defects: Table 5 (OLS results)
  split across two pages via ContinuedFloat; appendix landscape table
  compacted. Build now has 0 overfull vboxes; no values changed.
- README badges updated (60 pages, 69 verified references, v1.1).
