fix: compute notification stream silently died on uncaught exceptions 
Two exception paths could permanently kill the compute notification
chain (no more compute.updated events, no reconnection until a server
restart):

- connect() only caught ComputeError, but _run_http_query translates
  HTTP status errors (401/403/404/...) into sibling ControllerError
  subclasses (and a raw fastapi HTTPException for unexpected statuses).
  Those escaped the fire-and-forget connect() task started at controller
  startup and died silently. Now they notify clients, schedule an
  exponential-backoff retry, and still re-raise for explicit callers.
  The dead web.HTTP* except branches (never reached since
  _run_http_query converts HTTP errors itself) are removed.

- _connect_notification() only caught aiohttp.ClientError. A malformed
  frame (e.g. missing 'action') or any error raised while dispatching a
  compute event (e.g. a pydantic ValidationError in
  node.parse_node_response) escaped the task, skipped the reconnect
  scheduling placed after the try block, and killed the stream forever.
  Now any exception is logged with its traceback (the gather() future
  holding it was never retrieved, so nothing was ever printed) and the
  reconnect scheduling + final compute.updated emit live in the finally
  block so every exit path recovers.

Also moves the usage-stats reset before the disconnect log line so the
emitted compute.updated snapshot is consistent.
