Encode the Schedule 1 Part 2/3 points thresholds as parameters and add `pip_dl_points` / `pip_m_points` person-level inputs. The existing `pip_dl_category` and `pip_m_category` enums now have formulas that derive the award category from points; data-set-supplied categories continue to win because OpenFisca treats inputs as authoritative over formulas. This is the first slice toward the full points system. Per-activity descriptor inputs and an FRS imputation step are intentionally left for follow-up PRs.

Summary
First slice of the PIP points-based assessment from Schedule 1, Parts 2 and 3 of the Social Security (PIP) Regulations 2013.
gov.dwp.pip.{daily_living,mobility}.points_thresholds.{standard,enhanced}parameters (8 / 12 points per the regulations).pip_dl_pointsandpip_m_points.pip_dl_categoryandpip_m_categoryenums that derive the category from points. OpenFisca treats inputs as authoritative over formulas, so the existing FRS-supplied categories continue to win and baseline microsim runs are unaffected.This is intentionally a small, non-breaking foundation. Per-activity descriptor inputs (10 daily living + 2 mobility) and an FRS imputation step that decomposes existing category awards into descriptor scores are left for follow-up PRs — they are heavier and need data review.
