serrastkirin: Hesabkirina pool account bi blake2 hash

- poolAccountIds fonksiyona API tune ne, ji ber vê hataye derket
- Niha pool account bi AccountIdConverter û blake2 hash tê hesabkirin
- PalletId "py/ascon" bi (u32, u32) poolId re tê hash kirin
- Ev guhertin hem ji bo AddLiquidityModal û hem jî PoolDashboard

Taybetmendî:
✅ Add liquidity niha bi rast dixebite
✅ Pool metrics rast têne xuyakirin
✅ Reserve balances rast têne hesabkirin
✅ LP position tracking çêbû
