Function extractCampaignFundraisingEventAmounts

Extract the standard "campaign amounts + fundraising-event pooled amounts" breakdown used by the fundraising-dashboard family of overlays.

Rules (preserved from the overlay's original hook):

• campaign.amount_raised → campaignRaisedAmount (raw).
• fundraisingEvent.total_amount_raised → fundraiserRaisedAmount, and updates overallRaisedAmount to max(prev, fundraiserRaised).
• When the campaign has raised less than the event total, fundraiserRaisedAmount is capped to the campaign figure so a campaign-scoped progress bar can't overshoot its own contribution.
• When no fundraising event is provided, overallRaisedAmount falls back to campaign.total_amount_raised.
• fundraisingEvent.goal populates fundraiserGoalAmount and (when forceCampaignGoal !== true) overallGoalAmount.
• campaign.goal populates overallGoalAmount as a fallback.

The campaign-scoped scalars (goalAmount, currentAmount, originalGoalAmount) are delegated to extractCampaignAmounts for parity with useCampaignAmounts.

The React-flavored twin is useCampaignFundraisingEventAmounts in @playlive/react-query.
