fix(oracle-l8-r2): scrub raw endpoint from Inspector action toast

Oracle narrow FAIL on sha-a02cc70e: Inspector.tsx:91 still emitted
'Switch to LIVE mode + sign in to execute "..." against
/api/runtime/transactions/{id}/actions/{actionId}.'

Rewritten as 'Switch to live mode and sign in to run "..." on this
case.' Matches the LeftRail and Approvals toast voice.

Source grep for user-visible /api/ in pushToast/title/JSX text returns
zero matches.
