[FEATURE] Allow more frequent local routines

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Today, local routines can only run at most once per hour. I'm not sure why this restriction exists since you can work around it with /loop Xm xyz or with duplicate hourly routines. I expect this is for cloud routines but it's extended to local.

Proposed Solution

Allow any valid cron expression for local routines. Or at minimum allow sub-hourly cron expressions.

Alternative Solutions

I am working around it by making duplicate hourly routines that run on different points in the hour 🙃 .

A more user-friendly solution would be a better "custom" scheduler, but that would be gravy.
