Subject: [PATCH] fix(sync): restrict room refreshes to selected session to
 prevent flickering

- Optimized background API refreshes to focus on the selected session instead of the entire room.\n- Eliminated redundant bulk database writes that were causing UI flickering during refresh cycles.\n- Staggered initial data fetches to prevent API request storms.\n- Added detailed logging for easier tracing of background sync operations.
