Subject: [PATCH] qt: HD wallet status indicator in status bar

Add a [HD] label next to the lock icon that shows whether the
wallet has a BIP39 HD seed active:
  - Red (#f26522, TRI brand color) when HD is enabled
  - Grey (#555555) when wallet is non-HD (legacy key pool)

Tooltip on hover explains what HD means and what the user must
back up to be able to restore the wallet.

Wired through a new updateHDStatus() slot that reads the
public WalletModel::hdEnabled() accessor and is called when
the wallet model is set. Lives in the icon cluster of the
status bar; the .onion and .b32.i2p address text sits in a
separate group on the right, so no crowding.

Closes the visible-state gap: the wallet already supported
HD seeds (BIP39/BIP32) and had a hdseeddialog, but there was
no visual confirmation of HD status anywhere in the UI.
