Resolves TECH-07. Copies the four validators actually used
(requiredValidator, emailValidator, urlValidator, regexValidator) from
@core/utils/validators into packages/form-schema/src/utils/validators.ts
as pure boolean functions. Vuexy template copies in apps/*/src/@core/
remain for non-form UI use. Package is now genuinely standalone —
grep -rn "@core/" packages/form-schema/ returns zero matches.
Also corrects two documentation inconsistencies from commit 42dd626e:
dev-guide heading translated to Dutch for style consistency, and the
BACKLOG entry renumbered from TECH-DEBT-01 to TECH-07 to match the
flat numbering in the Technische schuld section.

Moves formBuilder types, formValidation, useConditionalLogic, useFormSteps,
and formatFieldValue from apps/portal/src to packages/form-schema/src.
Adds @form-schema path alias to both apps/portal and apps/app.
Vue field components remain per-app to allow independent visual evolution.
Behavior-neutral: all 35 Vitest tests green.
