fix(chain): canonical RLP for BSC sweeps + official RPC default

Browse Source 
- EthSigner: encode r/s as minimal big-endian bytes (even-length only)
  instead of zero-padding to 32 bytes. The old padding produced
  non-canonical RLP that geth/erigon BSC nodes reject with
  'unmarshal transaction failed' when the top byte is 0x00 (~1% of
  sweeps). Fixes broken BNB/USDT-BEP20 auto-sweep.
- coruna.bsc.rpc_url default: switch from third-party
  bsc.publicnode.com to official BNB Chain Foundation
  https://bsc-dataseed.bnbchain.org (free, no API key).
