fix🐛: getVerifyXxx's pk parameter type follows GoType, not always number

ts.go.template hardcoded the pk parameter as `: number`. vue.go.template
(F4, landed after this file) derives $pkType per table - "number" unless
the pk column's GoType is "string" (natural keys do exist; sys_tables.go
gives a pk column GoType "string" whenever its ColumnType is not
int-shaped), then types useForm on that same $pkType. A string-pk table
therefore generated a page calling get{Class}(id: string) against an api
module whose get{Class} only accepted number - a TS compile error, not
a runtime bug, and exactly the kind of gap each side's own template-only
verification could not see (F4 was checked against a hand-written .ts
stub before this template existed; this template was checked against a
numeric-pk fixture only).

Copies vue.go.template's $pkType derivation verbatim so both templates
agree by construction rather than by convention.

Verified: generated both a numeric-pk and a string-pk table's api module,
copied both into go-admin-ui and ran vue-tsc --noEmit - clean. Added a
throwaway call-site file exercising getVerifyStrPk with a string and (via
@ts-expect-error) confirming a number argument is now rejected, so the
type is actually enforced rather than having quietly widened to any.
