PoX error code mapping shifted

[jannik-stacks]

PoX error code mapping is wrong — verified against the canonical pox-4 contract

We compared the POX4_ERRORS map in this SDK against the actual pox-4.clar source in stacks-core. The SDK's mapping is wrong for 12 out of 13 codes from 19 onward. When a stacking tx fails, users are seeing the wrong error message.

Also checked @stacks/stacking is missing the new signer-related codes 32–40.

Looks like the SDK mapping is shifted. Maybe generated from increasing ints, but missing an error case.

Relevant code

• This repo: src/utils/constants.ts L87–L233 — the POX4_ERRORS map
• This repo: src/utils/helpers.ts L312–L322 — parseClarityErrCode() that reads these codes
• Canonical source: pox-4.clar in stacks-core — the actual contract
• stacks.js: packages/stacking/src/constants.ts L101–L130 — correct for 18–31 but missing 32–40

Fixed to the correct error codes provided.
