Closes dbeaver/pro#11582

Summary

• Enable the existing Tycho 5.0.4 core extension at the repository build entry points.
• Remove 5 redundant bundle POMs; derive coordinates and versions from PDE metadata.
• Preserve custom bundle POMs, module/profile selection, inherited build steps, and existing packaging.

Validation

• Maven validate passed for this reactor.
• Before/after effective-model comparison passed: same project set, coordinates, versions, packaging, dependencies, plugins, executions, resources, repositories, and profiles (ignoring timestamps and derived display metadata).

Full product verification is currently blocked by an existing execution-environment mismatch: org.jkiss.utils requires JavaSE-21 while com.dbeaver.jdbc.api (and LM API in Pro) resolves against JavaSE-17. The same failure was reproduced in the unchanged dbeaver-common reactor using mvn -pl :com.dbeaver.jdbc.api -am verify.

Coordination

Part of the cross-repository migration tracked in dbeaver/pro#11582. Matching branch: dbeaver/pro#11582-tycho-pomless-bundles. Merge the packaging/Jenkins compatibility changes before bundle removal; dependent builds should use the matching branches.

AI-assisted implementation and validation (OpenCode).
