fix(tests): isolate SCIM bad-id test from shared postgres state

[TheusHen]

Description

The go job failed in the Race step: TestSCIMBadID created its admin user with a fixed email while the same Postgres service had already been used by the earlier Test step, so the second pass died on duplicate key ... users_email_key. Every other API test already uses a timestamped email — this one was the odd one out. Also fixed the SC2035 glob in the release checksum step while I was in there.

Type of change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

How has this been tested?

• go vet ./internal/api/ — clean
• go build ./... — clean
• go test -run TestNothingMatchesThis ./internal/api/ — compiles, ok (full suite needs the Postgres service from CI)
