M9 margin per repair
- New non-stored computes on repair.order: x_fc_revenue, x_fc_labour_cost,
x_fc_parts_cost, x_fc_margin, x_fc_margin_pct.
- Revenue: sum of posted out_invoice.amount_untaxed on the repair's sale
order (handles partial / multi invoice scenarios).
- Labour: sum of (task.duration_hours x technician.x_fc_tech_cost_rate)
over COMPLETED visits only - avoids counting scheduled-but-not-done time.
- Parts: sum of standard_price x qty for stock moves where
repair_line_type='add' (parts consumed, not removed).
- New 'Margin' notebook tab on repair.order form, manager-group gated.
M7 failure analytics on the dashboard
- Three new keys in get_dashboard_data():
* failures_by_product - top 8 products by repair_count in last 90 days
via _read_group (efficient - no record load)
* failures_by_symptom - top 8 x_fc_issue_category values
* margin_summary - revenue/labour/parts/margin/margin_pct + sample_size
over the same 90-day window
- Three new tiles on the OWL dashboard 'Last 90 Days' section:
Margin Summary (revenue/labour/parts/margin breakdown),
Failure Rate by Product, Failure Rate by Symptom.
- New formatMoney + formatPercent helpers on the dashboard JS so values
display as 'CAD 12,345' rather than raw floats.
Verified end-to-end on local westin-v19:
Dashboard returned all 9 expected keys.
Top product: 'M6 X 27 THREADED BARREL' (2 repairs) - actual test data.
Margin summary over 26 repairs (dev has $0 invoices so values 0.0,
but the compute path is exercised and shapes are correct).
Bumped to 19.0.1.6.0.
