fix(quota): show seconds in reset countdown when less than a minute remains

[airvzxf]

Summary

Fix the mmx quota reset countdown so that when less than one minute remains until a quota window resets, the cell falls back to seconds (Xs) instead of rounding down to 0m, which currently makes the last minute look identical to "already reset".

Motivation

After #240 was implemented (#243), the reset countdown for each window (5h Reset …, 1d Reset …, etc.) drops the seconds component and only renders hours + minutes. Once the remaining time crosses below 60s, the minute unit rounds down to 0m, so the cell reads 5h Reset 0m (or 1d Reset 0m for the daily window). That is misleading: the window has not actually reset yet, there is just under a minute left, and the user has no way to tell that from the table.

Showing seconds for the last minute keeps the countdown continuous and accurate all the way down to zero, which matches the unit ladder already used in the proposed weekly cell from #248 (1w Reset 54s, 1w Reset 9s).

Steps to Reproduce

1. Run mmx quota (or mmx --verbose quota show) while the 5-hour rolling window has between 1s and 59s left until reset.
2. Observe the 5h Reset … cell.
3. The cell shows 5h Reset 0m instead of the actual remaining seconds (e.g. 5h Reset 38s).

Suggested Behavior

• When the remaining time is >= 1 minute, keep the existing format (Hh Mm).
• When the remaining time is < 1 minute, fall back to seconds: Hh Reset Xs (or Xd Reset Xs, depending on the window).
• Once the countdown reaches zero, the cell can read Reset now or stay blank — happy to align on whichever feels consistent with the per-row behavior.

Discussion & Implementation

Same offer as in #240 and #248: happy to discuss and adjust this fix based on feedback, and if the maintainers approve, I can implement the change and open a pull request.

cc @SaladDay — this affects the same reset cell introduced in #243, and would also unblock the < 1 minute example shown in #248.

[SaladDay]

Thanks for the clear report. I confirmed the boundary case: positive remains_time values below 60 seconds currently fall through to the minute formatter and render as 0m.

I’ll prepare a narrowly scoped fix that:

• renders positive durations below one minute in seconds;
• preserves the existing output for durations of one minute or more and for the zero/expired state;
• adds boundary coverage around 60 seconds and zero.

The weekly-header proposal from #248 and any broader quota-table formatting changes will remain out of scope for this fix.
