[I] [server] Support configurable DAY auto-partition format yyyy-MM-dd [fluss]

gyang94 opened a new issue, #3557:
URL: https://github.com/apache/fluss/issues/3557

   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.
   
   
   ### Motivation
   
   ## Motivation
   
   Today, auto-partitioned tables with `table.auto-partition.time-unit=DAY` always use `yyyyMMdd` as the partition value format.
   
   This is limiting in cases where users want DAY partitions to be organized in a more readable and conventional date form such as `yyyy-MM-dd`. It also aligns better with typed `DATE` partition values, which are naturally represented in dashed form.
   
   ### Solution
   
   Introduce a new table option:
    - `table.auto-partition.day-format`
   
   Supported values:
     - `yyyyMMdd` (default, backward compatible)
     - `yyyy-MM-dd`
   
   Behavior:
     - this option only applies when `table.auto-partition.time-unit=DAY`
     - when set to `yyyy-MM-dd`, all DAY auto-partition behavior
   should use dashed format consistently:
       - auto pre-created partitions
       - manual partition creation validation
       - writer-side dynamic partition creation
       - retention / expiration logic
