URL: https://github.com/apache/doris/pull/55426
### What problem does this PR solve?
When max_meta_object_cache_num = 0, the desc command fails because it tries
to access disabled meta cache.
#### Error reproduction:
When use_meta_cache = true (shown in catalog properties), executing desc
t_ts_ntz; fails with:
```
ERROR 1105 (HY000): errCode = 2, detailMessage = Unknown table
'7311664922056505694'
```
When use_meta_cache = false is explicitly set, the same desc t_ts_ntz;
command works correctly
#### Solution
- Force disable use_meta_cache when max_meta_object_cache_num = 0
- Add validation for invalid configuration values
- Add warning logs when cache settings are adjusted
- Improve code readability
