Vamsidhar - add time log summary component and fix timer display issues

[vamsidharpanithi]

Description

This PR fixes the Time Log Visibility issue on the Member Group Check-In page by adding a Time Log Summary component and fixing multiple timer display bugs. The summary table now displays all completed time logs with member names, roles, start/stop times, and durations. Additionally, fixed issues where timers were starting from incorrect values, not preserving paused/resumed states, and clearing the time when stopped.

Fixes # (bug list priority: Medium) - Time Log Visibility Issue on Member Group Check-In Page

I’ve reviewed this PR and tested the changes locally. Everything is working as expected.
• The Time Log Summary component renders correctly and displays completed logs with accurate member names, roles, start/stop times, and durations.
• Timer behavior issues are resolved — timers now start from 00:00:00, preserve paused/resumed states correctly, and clear properly on stop.
• No regressions observed on the Member Group Check-In page.
• I also verified the changes using before and after screenshots, and the improvements are clearly reflected.

Overall, the implementation looks solid and aligns well with the related backend changes.
