hailin 51c0f59924 fix(tss): remove threshold-1 in signing to match keygen exactly
The signing code was using thresholdT-1 while keygen was using thresholdT,
causing Lagrange coefficient mismatch and "U doesn't equal T" error in round 9.

Root cause: commit d0c504dc added -1 to signing threshold to "match user expectation",
but this broke the keygen/sign consistency that TSS-lib requires.

Changes:
- tss-party/main.go: Sign now uses thresholdT (same as keygen)
- pkg/tss/signing.go: Add logging, emphasize threshold must match keygen
- tss-wasm/main.go: Add comment about threshold consistency

NOTE: This fix maintains backward compatibility with existing wallets.
No wallet regeneration is needed.

ROLLBACK: If this causes issues, revert to commit before this one.
Previous signing threshold was thresholdT-1 (commit d0c504dc).
