Add a Client Script (fixture) that computes all derived cells of
"Declaration of value added tax" on manual edit, matching the e-taxes
form (verified against the live site):
- appendix roll-ups (parent = Σ children) for Əlavə 3/4/5 and debitor 307
- passthrough appendices → turnover (301.1←Əlavə3, 302←Əlavə4,
303←Əlavə5, 301-2←agro sold); agro purchased = Σ Hissə 1
- rates (18/20%, Art.174.5 50% relief), %-share lines, clamps, 326/327 net
- Əlavə 1 / Əlavə 8 page totals
Mark every computed cell read-only (per-column, or per-row via
read_only_depends_on). Guard recompute against the formula_editor
report-fill storm ("fill mode") so selecting dövr no longer hangs.
Additive — existing scripts (formula_editor, row-creators) untouched.
