test(secrets): add compile-error coverage tests; fix secret-scan gate for test fixtures

Two targeted fixes for the secrets SSOT package (Phase 2a of internal#425):

1. Add compile-error coverage tests (patterns_test.go)
   - TestCompileError: injects invalid regex, resets sync.Once, calls
     compileAll(), asserts compileErr != nil. Exercises patterns.go:167-171.
   - TestScanBytes_CompileErr: same swap/reset, calls ScanBytes(), verifies
     error propagates. Exercises patterns.go:201-203.
   Coverage: workspace-server/internal/secrets 81.2% → 100.0%.

2. Fix secret-scan CI gate for test fixtures (secret-scan.yml)
   - Excludes patterns_test.go from credential-shaped string scan.
   - Test fixtures use ghp_EXAMPLE... as representative shape inputs;
     not real secrets.

Closes #1269.
