Bump ddf.version to 2.29.33

[jaymcnallie]

Summary

Bumps <ddf.version> from 2.29.32 to 2.29.33 on master in preparation for cutting ddf-ui-5.2.34 against the latest DDF 2.29.x patch.

This keeps ddf-ui's release cadence aligned with DDF 2.29.x:

ddf-ui	targets ddf
5.2.32	2.29.29
5.2.33	2.29.32
5.2.34 (this PR)	2.29.33

No transitive dep bumps — DDF patch releases don't move Karaf, Pax-Web, CXF, or Jetty majors. karaf 4.4.8, pax-web 8.0.33, cxf 3.6.7, jetty 9.4.58.v20250814, tika 3.2.2, camel 3.22.4 remain as currently pinned.

Draft status

Opening as draft because ddf-2.29.33 is in flight but not yet published to repo.codice.org/repository/maven-public/ as of this PR open. CI will fail to resolve ddf:ddf-parent:2.29.33 until the upstream release lands. Marking ready-for-review once the artifact is available.

Test plan

• ddf-2.29.33 published to Nexus
• PR CI green (incremental + integration)
• Cut ddf-ui-5.2.34 via release.yml after merge
