- Move the call-type select handler into onCallType() — OWL cannot compile a
multi-statement inline t-on body (was a render-breaking crash on mount).
- Replace color-mix() inside border shorthands with var(--sb-border) (Odoo-19
SCSS drops color-mix in a border shorthand).
- Technician placeholder option value '' (not 'false') so the required-tech
guard isn't bypassed.
- Remove dead setTiming(); null-coalesce the refdata onWillStart load.
