fix(home): Nodes→Pockets action pill + remove active-Pocket chip

Re-apply the requested home changes that a concurrent edit reverted: the
"Nodes" action pill (→ /masternode) becomes "Pockets" (→ /pockets), and the
active-Pocket chip under the balance is removed. Clean-cut the now-orphaned
code — pocketSwitcherControl, activePocket/activePocketName, the pockets/
activeAccount/isWatchOnly selectors, the PocketSwitcherSheet dialog, and the
HubIcon/PocketAvatar/PocketSwitcherSheet/findPocket imports. Pockets is now
reached solely via the action pill; the pull-to-refresh hook extraction is
preserved untouched.
