   ### Search before asking

   ### Version
   
   apache/kvrocks:nightly-20261014-d690353, Linux arm64
   
   ### Minimal reproduce step
   
   On a local test instance at port 6666, with redis-cli:
   ```bash
   k="upstream-repro-$(date +%s)-$$"
   r() { redis-cli -p 6666 "$@"; }
   r HSET "$k" f v
   r HDEL "$k" f
   r EXISTS "$k"
   r TTL "$k"
   ```
   
   ### What did you expect to see?
   
   TTL -2 because the key no longer exists, as in Redis.
   
   ### What did you see instead?
   
   EXISTS returns 0 but TTL returns -1.

   _No response_

   Hi, I’d like to give this issue a try. I’ll investigate why TTL returns -1 after the last hash field is deleted and add a regression test. Thank u！
