Adds three usability improvements to the marja internă feature:
1. Settings UI section "Marjă internă (nu TVA)" — configurable at tenant level
2. Per-line toggle "Aplică marjă" on each manoperă
3. Global visibility flag to hide margin details in-session
== 1. Settings page ==
New section on /app/settings (gated by FINANCE_VIEW_INTERNAL_MARGIN):
- "% marjă implicit" numeric input with % suffix, 0–90 range
- "Afișează detalii marjă la procesele calculate" toggle (default on)
- Explicit label "Marjă internă (nu TVA)" plus helper text explaining
it's not the Moldovan tax — feeds into MarginResolver as the tenant
default, applied only when the mechanic has no per-user margin.
Persists as company.settings.default_internal_margin_pct and
company.settings.show_internal_margin_details.
== 2. Per-line "Aplică marjă" toggle ==
New wo_works.apply_margin boolean, default true. When false:
applied_margin_pct = 0
salary_base = total (mechanic gets salaried on the full amount)
Use case: oil change, tire mount, and similar "at-cost" services where
the shop doesn't want to hold back part of the labor rate. The owner
can flag those specific lines while keeping margin on diagnostic and
premium labor.
WorksRelationManager form gains a Toggle field (gated by
FINANCE_VIEW_INTERNAL_MARGIN); table gains a ToggleColumn for quick
inline flipping without opening the row.
Booted hook now recomputes salary_base when apply_margin is dirtied,
so toggling live in the table takes effect immediately.
== 3. Show internal margin details flag ==
Global tenant flag (default on): when off, the gray subtitle line
"Bază salariu: 200 · marjă 20%" under the Total column disappears for
everyone, even users with FINANCE_VIEW_INTERNAL_MARGIN.
Practical use: when reviewing a Fișă face-to-face with the client on
the manager's screen, flip the flag off from Settings for the day →
no risk of the client accidentally seeing internal numbers. Flip back
when done.
The flag lives in company.settings.show_internal_margin_details.
== Description text on the Total column ==
Now shows either:
- "Bază salariu: 200.00 MDL · marjă 20%" when apply_margin=true
- "Fără marjă · bază salariu = Total" when apply_margin=false
- nothing when show_internal_margin_details=false or role lacks permission
== Tests ==
InternalMarginToggleTest (5):
- apply_margin=false → salary_base equals total, applied_margin_pct=0
- apply_margin=true (default) still applies 20% margin
- Toggling apply_margin recomputes salary_base bidirectionally
- Company default margin resolves when mechanic has no per-user setting
- show_internal_margin_details flag persists correctly in Company.settings
Suite: 303 passed (845 assertions). Was 298.
