fix: set explicit width on custom time input example

[balajis-qb]

Description

Problem
The "Custom Time Input" docs example (docs-site/src/examples/ts/customTimeInput.tsx) leaves the custom <input> without an explicit width. It falls back to the browser's default text-input width, leaving a large empty gap next to the short HH:MM value.

Changes
Added an explicit width: 70px to the input's inline style so it's sized appropriately for the time value instead of relying on the browser default.
