Addresses errcheck, gosec, revive, staticcheck, and unused findings
across the codebase (unchecked error returns, unsafe file inclusion
warnings on operator/test-controlled paths, missing package comments,
unused parameters, deprecated API usage). Also fixes two suppression
comments that were silently no-ops due to wrong syntax (#nosec needs
a leading '#', nolint reasons need '//' not '--').
With the backlog clear, drop continue-on-error from the CI lint job
per the plan left in b4b4806.

Callers can now supply a plain-text Body alongside an HTML html_body;
the SMTP sender emits multipart/alternative using both verbatim instead
of auto-stripping HTML to derive the plain-text fallback. The legacy
content_type=HTML path is preserved (deprecated) for existing callers.

- Use typed context key for auth context to prevent collisions (auth.go)
- Eliminate nested locking in CheckRateLimit to prevent potential deadlock (auth.go)
- Add 1MB request body size limit middleware to prevent DoS (router.go)
- Return proper gRPC status codes instead of nil errors on failures (handler.go)
- Use key name instead of raw API key in admin URL paths to prevent secret leakage (keys.go, router.go, keystore_db.go, keystore_hybrid.go)
- Enforce RBAC authorization in service Send/SendBatch for both REST and gRPC (service.go)
- Pin runtime Docker image to alpine:3.21 for reproducible builds (Dockerfile)
- Enable readOnlyRootFilesystem with /tmp emptyDir in k8s deployment (deployment.yaml)
