feat(npa): add Undebited Interest Recovery Report, fix note text width

Adds a 10th NPA report tracking memorandum "undebited interest" per IRAC
norms (accrued vs cash-recovered vs balance), wired into Export to Excel
and the NPA mega-menu. Also fixes a narrow-width text wrap on the report's
description note (new .npa-report-note class overriding pg-sub's 560px cap).
