   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
   
   
   ### Paimon version
   
   1.2.0
   
   ### Compute Engine
   
   spark 3.5
   
   ### Minimal reproduce step
   
   1. create table
   ```
   CREATE TABLE .main.test (
       order_id          STRING,
       order_price       DOUBLE,
       order_date        DATE
   )
   USING paimon
   PARTITIONED BY (order_date)
   TBLPROPERTIES (
     'bucket-key' = 'order_id',
     'bucket' = '16',
     'primary-key' = 'order_date,order_id',
     'deletion-vectors.enabled' = 'true'
   );
   ```
   
   2. insert some record
   ```
   INSERT INTO ai_bidding_paimon_dev.main.test VALUES
   ('order_001', 1.0, '2025-10-10')
   ```
   
   3. try to use `expire_partitions`
   ```
   CALL sys.expire_partitions(
       table => 'main.test', 
       expiration_time => '1 d',
       timestamp_formatter => 'yyyy-MM-dd',
       timestamp_pattern => '$order_date',
       expire_strategy => 'values-time'
   )
   ```
   
   ### What doesn't meet your expectations?
   
   Result will be `No expired partitions.`
   ```
   WARN PartitionValuesTimeExpireStrategy: Can't extract datetime from partition order_date:20371.
   ```
   But I think the `expire_partitions` procedure should be type-aware. It should correctly interpret the value of a DATE partition column and compare it with the expiration time.
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [ ] I'm willing to submit a PR!
