Merge 'bindings/java: Implement setObject(int, Object) in JDBC4PreparedStatement' from Orange banana

Browse Source 
## Purpose
* Implement `setObject(int, Object)` to support binding of common Java
types to SQL parameters in JDBC4.
* This implementation currently covers only standard JDBC4 supported
types. LOB and stream bindings are not yet implemented.
## Changes
* Implemented JDBC4PreparedStatement#setObject(int, Object) handling for
  * `String`, `Integer`, `Long`, `Boolean`, `Double`, `Float`, `Byte`,
`Short`
  * `byte[]`, `Date`, `Time`, `Timestamp`, `BigDecimal`
* Added validation for unsupported types (`Blob`, `Clob`, `InputStream`,
`Reader`)
* Added corresponding unit test `testSetObjectCoversAllSupportedTypes`
to verify correctness
## Note
* Additional work (e.g., LOB/Stream handling) will be addressed
separately once driver support is available.
