Three fixes for the non-functional budget system:
1. Fireworks models hardcoded cost {input: 0, output: 0}, making all
Fireworks/Fire Pass runs report $0 and budget enforcement useless.
Added per-model pricing to FIREWORKS_CURATED_MODELS with a fallback
for unknown models. Pi-ai known providers (Anthropic, OpenAI, etc.)
already had correct per-model pricing via getModels().
2. saveAgent IPC handler passed the form's submitted status through
without checking whether the agent was budget-paused and the new
budget exceeds spent. Now auto-resolves paused → idle when the user
raises budget_monthly_usd above spent_monthly_usd.
3. checkAutoResolve in budget-enforcement-service resolved policy
incidents but never touched agents.status. Added
unpauseBudgetBlockedAgents() that scans for paused agents whose
legacy budget now has headroom and flips them to idle.
