Add EXPIRED_AFTER column to TASK_LOCK table

Add a new `EXPIRED_AFTER` timestamp column to the TASK_LOCK table
across all supported database schemas. This column supports automatic
lock expiration functionality by tracking when a lock should expire.
This feature was added by Spring integration as discussed in its
migration guide:
https://github.com/spring-projects/spring-integration/wiki/Spring-Integration-6.x-to-7.0-Migration-Guide#new-distributedlock-api

The column is added as a non-null timestamp field in the following
database schemas:
- DB2
- H2
- HSQLDB
- MariaDB
- MySQL
- Oracle
- PostgreSQL
- SQL Server

resolves #960
