Fix testifylint violations in trial_dry_run_test.go

[Copilot]

The lint-go workflow was failing on two testifylint violations where assert.NoError should be require.NoError for critical error checks.

Changes

• Line 272: assert.NoError → require.NoError for dry-run execution error
• Line 336: assert.NoError → require.NoError for dry-run mode error

Rationale

Testifylint enforces using require.* for error assertions that are prerequisites for subsequent test logic. Both assertions guard operations where test continuation on error would be meaningless.

// Before
assert.NoError(t, err, "Dry-run should not error")

// After  
require.NoError(t, err, "Dry-run should not error")
