[Frontend] IncomingStreams formatTokenAmount mis-scales already-human amounts

Why this matters

In frontend/src/components/IncomingStreams.tsx:

function formatTokenAmount(value: number, decimals = 7): string {
  if (!Number.isFinite(value)) return '0.0000000';
  return formatAmount(BigInt(Math.floor(value)), decimals);
}

value here is an already human-scaled token amount (the Stream mapper in lib/dashboard.ts divides raw stroops by 1e7). Passing it through formatAmount(BigInt(Math.floor(value)), 7) re-interprets it as raw base units and floors it, so e.g. 10.5 renders as 0.0000010 instead of 10.5. The Deposited/Withdrawn/Claimable columns in the incoming-streams table therefore show wildly wrong (tiny) numbers.

Acceptance criteria

• Format the human number directly (e.g. Intl.NumberFormat with up to 7 fraction digits, as IncomingStreamCard does) rather than round-tripping through formatAmount for base units
• Deposited/withdrawn/claimable display the correct magnitudes

Files to touch

• frontend/src/components/IncomingStreams.tsx

Out of scope

• The dashboard token/status mapping ([Frontend] Dashboard maps every stream to token 'TOKEN' and never reflects Paused/Cancelled status #553).
