BtcAddress::bech32Verify only checked the bech32 (BIP173) checksum
constant (=== 1), so valid Taproot addresses (bc1p, witness v1,
bech32m, const 0x2bc830a3) failed checksum verification and were
rejected as 'Invalid to address' by TransferService.
- bech32Verify now returns the detected encoding ('bech32' | 'bech32m' | null)
- decodeBech32 enforces BIP350 version<->encoding consistency
(v0 must be bech32, v1+ must be bech32m)
- scriptPubKey adds the P2TR (v1 + 32-byte) branch: OP_1 <32> = 5120...
- bech32Checksum/bech32Encode pick the correct constant per witness
version so Taproot encoding round-trips correctly

- 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.

bsc.publicnode.com to official BNB Chain Foundation
