Drop live badge + fiat price; persist wallet in sessionStorage

- Remove the online/live status badge and the USD price line, which both
  appeared after load and caused layout shift. Stop fetching price entirely.
- Persist the seed + passphrase in sessionStorage so a page refresh restores
  the open wallet instead of returning to the unlock screen. Cleared on
  logout and (by the browser) when the tab closes.

Note: sessionStorage holds the seed in plaintext for the tab session — an
acceptable tradeoff for this self-custody tool and scoped to the tab.
