Support for Break Times Less Than 1 Minute

[Sampson-Lee]

Is your feature request related to a problem? Please describe.
While using Pomatez, I've noticed that break times can only be set to a minimum of 1 minute. For certain work scenarios (such as specific types of focused work or high-intensity interval training), shorter break periods of 30 or 45 seconds would be beneficial.

Describe the solution you'd like
I would like the ability to set break times (both short breaks and long breaks) with a minimum value of 15 or 30 seconds, rather than being limited to 1 minute minimum. Specifically:

• Modify the minimum value constraint for break times to allow settings as low as 15 or 30 seconds
• Provide seconds options or fractional minute options (e.g., 0.5 minutes) in the break time settings interface
• Ensure related displays correctly handle time formats for durations less than 1 minute

Describe alternatives you've considered
Currently, I must resort to using external timers for breaks shorter than 1 minute, which disrupts the seamless experience of managing time within a single application. Or I just have a 1-min break, which kind of waste time and patience.

Additional context
Short breaks are valuable for certain work methodologies, for example:

• High-intensity interval training often uses 20-40 second rest periods
• Some variations of the Pomodoro Technique employ shorter breaks to maintain focus
• For certain creative work, longer breaks might interrupt thought processes

This enhancement would make Pomatez more adaptable to a wider range of work styles and methodologies while maintaining its clean design philosophy.
