feat(teams): member task progress reminder + fix broken progress notifications

- Fix progress event payload missing TaskNumber, Subject, OwnerAgentKey,
  ProgressPercent, ProgressStep — notifications were rendering empty
- Fix progress notification format to include task name (consistent with
  dispatched/failed) and guard empty ProgressStep
- Change percent tool schema from number to integer for clarity
- Add pre-run member task reminder injecting task context before LLM loop
- Add mid-loop progress nudge every 10 iterations with suggested percent
  based on iteration ratio (handles maxIter=0 unlimited case)
- Enhance leader cross-session reminder to show progress % when available
- Strengthen TEAM.md member guidance: focus, result quality, progress rules
- Add progress bar to task list table view (matches kanban card pattern)
