fix: stepper arrows on grid Columns and Rows inputs

[SmrutiSawant]

Problem
The up/down stepper arrows never render on the Columns and Rows inputs in the Layout section, though every other field has them.

Cause
BlockGridLayoutHandler binds a number (parseRepeatFunction uses parseInt), but Input.vue's isStrictNumber returned false for any non-string, so canShowArrows short-circuited.

Changes
Input.vue — isStrictNumber accepts finite numbers.

Before:

v1.mp4

Now:

v2.mp4

Confidence Score: 5/5

The PR appears safe to merge.

The finite-number check restores arrows for numeric grid bindings while rejecting NaN and infinities; no concrete regression was identified.
