   Controller for Server-Sent Events (SSE) streaming.

+  ## Error Handling
+
+  All error responses use structured JSON format for consistency with the API:
+
+      {
+        "error": "Human-readable error message",
+        "code": "MACHINE_READABLE_CODE",

+
+  ## Error Codes
+
+  - `SSE_GLOBALLY_DISABLED` - SSE disabled in server configuration
+  - `SSE_DISABLED_FOR_MAP` - SSE disabled for this specific map
+  - `SUBSCRIPTION_REQUIRED` - Active subscription required (Enterprise mode)
+  - `MAP_NOT_FOUND` - Requested map does not exist
+  - `UNAUTHORIZED` - Invalid or missing API key
+  - `MAP_CONNECTION_LIMIT` - Too many concurrent connections to this map
+  - `API_KEY_CONNECTION_LIMIT` - Too many connections for this API key
+  - `INTERNAL_SERVER_ERROR` - Unexpected server error
+
+  ## Access Control
+
+  SSE connections require:
+  1. Valid API key (Bearer token)
+  2. SSE enabled globally (server config)
+  3. SSE enabled for the specific map
+  4. Active subscription (Enterprise mode only)
