fix(cli): reject negative and fractional count/pagination flags in Danish portal CLIs (#191)

Bare z.coerce.number() accepted negative and fractional values for count/pagination flags, and slice(0, limit) with a negative limit silently dropped trailing results instead of erroring. Tightens the schemas to .int().min(1) across all four Danish portal CLIs (including jobnet occupations --per-page) with network-free validation tests.
