ac6ae69329 fix: implement BIP341 key tweaking for P2TR transaction signing 
This commit fixes P2TR (Pay-to-Taproot) transaction signing by properly
implementing BIP341 key path spending.

Key changes:
- Add SignSchnorrTaproot() method to CKey for BIP341 tweaked signing
- Implement ComputeTapTweak() and CreatePayToTaprootPubKey() in XOnlyPubKey
- Add GetTaprootInternalKey() to SigningProvider interface for internal key lookup
- Store taproot internal key mappings in LegacyScriptPubKeyMan
- Fix FindTaprootPubKey() to use internal key mapping with fallback
- Use empty scriptCode for Taproot key-path spending (per BIP341 spec)
- Update HaveTaprootKey() to verify tweaked keys correctly

Technical details:
- Internal keys are tweaked using secp256k1_keypair_xonly_tweak_add
- Parity handling is automatic via secp256k1 library
- Empty scriptCode ensures correct sighash for key-path spending
- Internal key to output key mapping stored for efficient lookup

Testing:
- P2TR address creation, funding, and spending work end-to-end
- Multi-hop P2TR transactions tested successfully
- All functional tests pass (feature_taproot.py, wallet_*, rpc_*)

Fixes: non-mandatory-script-verify-flag error on P2TR spending

49d13674e1 validation,policy,test: activate taproot flags and harden wallet fs checks 
Wire Taproot script verification into validation/policy/libconsensus and update standardness flags.

Adapt wallet_multiwallet functional test to match filesystem error variants (create_directory/create_directories/filesystem error), making the suite robust across fs backends and library versions.

613bcdbed7 encoding,test: backport BIP350 bech32m and align test vectors to Palladium 
- use Bech32 for witness v0 and Bech32m for witness v1+ in key_io
- update C++ bech32 tests and python segwit_addr framework
- realign key/address test vectors and fixtures to Palladium prefixes/params
- adjust chain-parameter-sensitive tests (maturity, BIP66/regtest, message verify)
- fix incorrect historical sha256 expected vector in unit tests
