Reduce TRU farm rewards by 30%

Reduce total TRU farming emissions by ~30% as follows:

1. Decrease tfUSDC emissions from 120,000 TRU/day to 60,000 TRU/day in total:
   • 48,000 TRU/day to tfUSDC farming via liquidity gauge
   • 12,000 TRU/day to tfUSDC/USDC liquidity pool (as approved by @rattlecage’s proposal here)
2. Reduce tfTUSD emissions from 27,000 TRU/day to 10,000 TRU/day
3. Leave tfUSDT and tfBUSD emissions as-is (current utilization rates in these pools are >90%)
