- Store SHA-256 digests (key_hash + key_preview) instead of raw keys, in
both the in-memory store and Postgres; migrate legacy plaintext rows in
place and drop the plaintext column.
- Fix TEXT[] scans that failed at runtime (missing pq.Array) in
GetKey/ListKeys/LoadAllKeys.
- Load persisted keys at startup (InitializeFromDatabase was never called)
and fall back to the database on cache miss, so issued keys survive
restarts.
- Make HybridKeyStore.CreateKey genuinely write-through: cache is only
updated after a successful DB write.
- Guard nil database backend (auth enabled without DB previously panicked
on key creation) and degrade to in-memory operation.
- Persist bootstrap admin keys when a database is configured.
- Record real audit-log details as JSON and log audit failures instead of
silently dropping them; add DB pool limits and ping timeout.
- Sentinel errors matched with errors.Is; unit tests for hashing,
write-through ordering, DB fallback, and nil-DB operation.

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)

- Normalize content_type to lowercase before processing to handle case-insensitive input (e.g., "HTML", "Html")
- Add validation in Validate() to ensure only valid content types are accepted
- Return descriptive error message if invalid content type is provided
- Fix condition in ToNotification() to properly detect and default content type
- Update SMTP notifier auto-detection to work correctly when content type is not explicitly set
Issues fixed:
1. Dynamically detecting content type now works correctly (was always defaulting to "text")
2. Client can now specify content type in request as "HTML", "html", or "Html" - all work
3. Invalid content types are rejected with clear error messages
4. Auto-detection still works if neither explicit type nor valid HTML markers are found
Example scenarios:
- No content_type field: auto-detects based on body (checks for <, <html, <!DOCTYPE, <p>, <div>, <br>)
- content_type: "html": sends as HTML with multipart/alternative
- content_type: "HTML": normalized to "html", sends as HTML
- content_type: "invalid": returns validation error
- content_type: "text": explicitly sends as plain text, skips auto-detection

After conflict resolution from rebase, some imports were accidentally
removed and the CORS middleware function was eliminated but still
referenced by tests. This commit:
- Adds fmt import to api/rest/keys.go (used for error messages)
- Adds gorilla/mux import to cmd/server/main.go (used for router type)
- Restores newCORSMiddleware function to api/rest/router.go for test compatibility
- Formats code with gofmt
Add comprehensive improvements across REST and gRPC APIs:
- Add structured logging for all notification operations
- Implement HTML email support with multipart/alternative MIME
- Add CC and BCC recipient support for email notifications
- Add GetNotifiers endpoint to query available notifier configurations
- Support configurable From name in SMTP configuration
- Auto-detect content type (text vs HTML) in notification bodies
- Improve error handling and validation across all endpoints
