refactor: move FlowPilot actions to header bar, fix dividers

- Moved Resolve/Escalate/Share Update buttons from fixed bottom bar into
  the session header. Desktop: inline buttons + overflow menu (Pause/Close).
  Mobile: single overflow menu with all actions.
- Removed FlowPilotActionBar from bottom — message input is now the only
  fixed element at bottom, giving more breathing room.
- Replaced jarring white dividers (var(--glass-border)) with subtle
  border-border (#2e3240) throughout FlowPilot session.
- Restyled status badge from button-looking element to dot + text indicator
  with semantic colors (green=resolved, amber=escalated).
- Reduced content padding from pb-32 to pb-24.
