1.5.0-beta.1

Summary

• Fix: days/hours remaining now update automatically (midnight refresh in day mode, hourly in hour mode)
• New sensors: Cycle period, Time elapsed
• New buttons: Step back / Step forward (adjust last reset by 1 day or 1 hour)

Test plan

• Day mode: wait until after midnight (or change system date) — days remaining decreases without reload
• Hour mode: wait 1 hour — hours remaining updates
• Step back 2× then check remaining (e.g. 14 → 12 on a 14-day cycle)
• Step forward corrects an accidental step back
• Reset still sets timer to now
