fix: correct critical bugs in DaemonSet templates

This commit fixes 2 critical bugs discovered during functional E2E testing:

**Critical Bug #1: DaemonSet Selector Label Mismatch**
- **Issue**: DaemonSet selector used static labels (`app`, `release`) while pod template used common-library labels (`app.kubernetes.io/name`, `app.kubernetes.io/instance`)
- **Impact**: Kubernetes rejects DaemonSet deployment with error: `selector does not match template labels`
- **Root Cause**: When migrating pod labels to common-library helpers, DaemonSet selector wasn't updated
- **Fix**: Updated both `daemonset.yaml` and `daemonset-windows.yaml` to use `newrelic.common.labels.selectorLabels` helper

**Critical Bug #2: VerboseLog Boolean Evaluation**
- **Issue**: Template compared boolean \$verboseLog variable as string \"true\" instead of boolean
- **Impact**: Setting `global.verboseLog=true` didn't set `LOG_LEVEL=debug` (silent configuration failure)
- **Root Cause**: Common-library `verboseLog` helper returns boolean value, but template used string comparison
- **Fix**: Changed condition from `eq \$verboseLog \"true\"` to `if \$verboseLog` in both Linux and Windows DaemonSets

Both bugs were found by functional E2E tests (helm-unittest doesn't validate Kubernetes API rules or boolean evaluation edge cases).
