Fix getProgramAccounts missing Token2022 pools (643 bytes vs 252)

DataSize(252) filter rejects Token2022 PumpSwap pools which are 643 bytes.
This causes find_by_mint to miss pools that already exist on-chain, leading
to unnecessary 45s+ wait loops during migration detection.

Remove the DataSize filter from find_by_base_mint and find_by_quote_mint —
the Memcmp filter on program-owned accounts is specific enough.

Also add diagnostic logging on find_by_mint failure for debugging.
