use configurable fastRefreshEvery for InitCmd on flame and stream tabs

Change tabDescriptor.InitCmd from func() tea.Cmd to func(*Model) tea.Cmd
so the initial tick for the flame and stream tabs uses the model's
fastRefreshEvery interval rather than hardcoded 200 ms constants.

Both call sites in Init() and postKeyTransitionCmd() now pass the model
pointer. The now-unused streamTickCmdFn/flameTickCmdFn package-level
adapters are removed; the TabFlame and TabStream registry entries use
inline closures that delegate to m.flameTickCmd()/m.streamTickCmd().
