chore: migrate from OSSRH to Sonatype Central Portal

Sonatype legacy OSSRH (s01.oss.sonatype.org) has been shut down,
causing 405 errors on snapshot deploys. Migrate to Central Portal:

- Replace nexus-staging-maven-plugin with central-publishing-maven-plugin
- Update distributionManagement to use Central Portal snapshot URL
- Update CI workflows to use server-id "central"
- Remove obsolete OSSRH releases repository

Note: repo secrets (SONATYPE_USERNAME/PASSWORD) must be replaced with
new Central Portal tokens generated at https://central.sonatype.com.
Snapshots must also be enabled for the namespace in the Portal UI.
