Retire the hand-rolled channel-manager view pills for the shared <Tabs> component (given an
optional className so it embeds in the justify-between header without the default mb-4), and
back view + layout on usePersistedTab instead of manual getAccountRaw/setAccountRaw useState.
That subsumes the account-pin re-hydrate (usePersistedTab now re-reads on the pin), so
ChannelsProvider's bespoke markManagerDirty/useAccountRehydrate is gone; setView keeps the
history-tab logic (_chTab pushState + popstate) layered on the stable raw setter, and
useAccountPersistedState's setter is now memoized so that stable action holds.
Per the user's call, unify every channel-manager pill on the rounded-lg idiom: the view tabs
via <Tabs>, the sync chips and tag chips + the "manage tags" affordance from rounded-full to
rounded-lg — no more odd-one-out rounded-full.
gate-green: tsc + vitest 120 + eslint-0 + knip + prettier. Self-E2E'd: tab switch, browser
Back across tabs (Blocked->Hidden->Subscriptions with localStorage in sync), and a fresh tab
restoring view=hidden on the FIRST load; zero console errors.
