fix(client/windows): left-align setting captions, drop the width cap, add auto-wake

Three follow-ups to the parity sweep:

- Captions read centred: a TextBlock defaults to Stretch alignment, so the
  MaxWidth cap left it floating in the middle of the leftover width instead
  of sitting under its control. Pin them (and the footers) Left.
- The settings column kept the shared page() 640px cap, which -- next to the
  NavigationView pane spending the left third -- squeezed the cards into a
  narrow ribbon. Drop the cap here.
- Auto-wake on connect (the Apple client's toggle) is now a setting rather
  than unconditional behavior. Default on, which is what it did before.
  Gating the flow's ENTRY, not its packet sends: with it off a failed dial
  just fails, instead of showing a "Waking..." wait that would never send a
  packet to end itself. The explicit "Wake" host-card menu action is
  deliberately NOT gated -- that is the user asking directly.
