applySnapshot was always setting isPaused = false and blockStartedAt = Date.now() regardless of the actual timer state, causing a paused block to appear running whenever the dashboard was reloaded. - Add is_paused field to DashboardSnapshot schema - Dashboard endpoint derives is_paused by checking whether the last start/resume/pause event for the current block is a pause - applySnapshot now reads is_paused from the snapshot instead of resetting to false, and only sets blockStartedAt when the block is actually running (not paused) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
