Is your feature request related to a problem? Please describe.
The convert_entry_type processor should detect the type of data in the string and auto convert it.

Describe the solution you'd like
For all string type fields in the event, the processor should auto detect the type and convert it to appropriate type.
For example
"flag":"true" should be converted to "flag":true (boolean)
"value":"10" should be converted to "value":10 (integer or long depending on the value)
"delta": "1.2e6" should be converted to "delta": 1.2e6 (double or float)
"date":"2025-05-30 14:22:07" optionally converted to epoch_millis or epoch_nanos

Describe alternatives you've considered (Optional)
