Summary

Closes #15

User-facing token amounts were passed directly to smart contracts without multiplying by 10^decimals, causing all swaps and liquidity operations to execute at dust amounts
Added toRawAmount/fromRawAmount utility functions for precise human↔raw conversion
Applied scaling in SwapPage (simulate, swap, balance check, Max button) and PoolPage (provide liquidity, withdraw liquidity, LP Max button)

Test plan

Enter a swap amount (e.g. 1000 EMBER) and verify the on-chain tx sends 1000000000 micro-units
Click Max on swap page — input should show human-readable balance, not raw micro-units
Provide liquidity with known amounts and verify pool reserves change by expected token amounts
Withdraw LP tokens and verify correct raw amount is sent
Verify insufficient balance check triggers correctly for amounts exceeding wallet balance
