fix(report,chart): blank columns — drop Kranti, split Ashtakavarga house SAV, ascendant nakshatra, engine varga dignity, no duplicate charts (BUG-1199..1203)

- Report p33 table: no Kranti column (no producer; materials.kranti stays blocked).
- Report p53 table: the "SAV" column was the with-Lagna total (386). Split in the
  reader into SAV / Lagna BAV / SAV + Lagna with a totals row; ashtakavarga.py is
  untouched (frozen rectification identity, ERR-115).
- /api/chart ascendant carries nakshatra / pada / lord (_nakshatra_fields shared with
  the nine bodies); chart cache schema 4 -> 5.
- /api/varga_full bodies carry dignity_level from varga_dignity_level, the function
  the Vimsopaka path now shares (A/B identical); the chart page shows the D1 status
  wording and no longer derives a three-level dignity itself.
- Report page draws each chart once: the trailing block skips charts the body already
  fenced (same rule as the export); the birth-time caveat moves under the body's
  chart heading.

 `57782aea` 改 `scripts/functional_benefics.py`（功能吉凶 v2）让原生打分同输入出不同分（reported-offset 900 例里 230 例变化），但该文件不在 `sealed_holdout_rerun.py` `PRODUCTION_FILES` 和 dataset `frozen_scoring.files` 里，`tests/test_rectification_validation_integrity_gate.py` 全绿；随后只把 `scoring_service.py` 的 `ALGORITHM_VERSION` 从 scoring-9 改成 scoring-10，同一门禁 8 条失败。冻结身份是显式审过的文件清单，不是传递依赖，清单外的打分输入会静默漂移。
 
 Prevention: 打分路径新增或改动输入模块时，先查它在不在两份清单里；`functional_benefics.py` 已补进 `PRODUCTION_FILES` 并由 `test_functional_roles_are_part_of_the_production_identity` 锁住；改动后按 ERR-110 重新冻结（本次标签 `functional_v2_2026_10_02`）。关联 BUG-1181、ERR-110。

+`TASK-report-chart-blank-columns-20261003` T2 写的是「`_map_to_houses_values` 增字段」，`scripts/ashtakavarga.py` 在 `sealed_holdout_rerun.PRODUCTION_FILES` 里，只加字段、分数不变也让 `test_rectification_validation_integrity_gate` 4 条与 `test_sealed_holdout_contract_freshness` 3 条失败（ERR-110 同型）。改为在 `pl9_reader_export.py` 用引擎已有字段拆分，冻结文件零改动，门禁恢复全绿，无需重新冻结。

+Prevention: 写任务书时（不只是执行时）就对照 `PRODUCTION_FILES` 与 dataset `frozen_scoring.files`；只为展示的字段优先在消费层（reader / mapper）从已有数据推出，不进冻结文件。关联 ERR-110、BUG-1200。
