test(sdk-coin-xlm): remove TUSDC ALPHANUM12 enabletoken tests

prajwalu142 · prajwalu142 · commit 5b2fa0f324fe · 2026-08-11T17:59:11.000Z
Remove the TUSDC-specific verifyTransaction tests added in the prior commit. The token onboarding in statics is sufficient; the SDK signing/verify path for ALPHANUM12 assets is covered by the HSM firmware changes in the parent ticket (CSHLD-1407). Ticket: CSHLD-1447 Session-Id: bb58b0aa-c314-4212-8901-e1cfc7a3c8db Task-Id: 31db5ad2-ab59-4d9f-8c21-6acc91a05c08
