Summary

• restore pre-fix: Remove clamping and add app store deny #335 clamped DeviceActivity intervals for one-shot timer activities
• keep interval start at 00:00 and cap same-day timer ends at 23:59
• recognize pause and strategy timer activities in debug output

Context

This is a focused hotfix for #352. PR #335 changed one-shot timer schedules to start at the current minute and wrap end times modulo 24. Pause timers rely on DeviceActivity interval start callbacks to lift restrictions and mark pause state, and v1.33 reports show that callback path no longer reliably starts.

Verification

• make lint (existing warnings remain in unrelated files)
• make build
