FOLLOW-UP: Stale docstring in timepicker.go

[adnaan]

Context

This follow-up task was identified during the review of PR #292.

Source PR: #292
Suggested by: @claude[bot], @Copilot

Task Description

The "Required lvt-* attributes" comment in components/timepicker/timepicker.go still lists lvt-click and lvt-input, but these are old syntax. The actual attributes used in the template are now onclick="..." and lvt-on:input. The docstring should reflect the current attributes.
