build: make the reactor root the single version source of every module

The release pipeline rewrites <revision> only in the ROOT pom.xml (the pinned legacy calculate_version.sh) and nothing passes -Drevision
(java-verify runs plain `mvn verify` with MAVEN_ARGS only from caller inputs), but every module declared its own <revision>0.1.0-SNAPSHOT</revision>
and did not inherit the root. After an RC rewrite the root would say the RC while the modules still built as the SNAPSHOT, so capture
(target/<artifact>-<root version>.jar) would find no JAR and the publisher (one version per reactor) would reject the reactor.

Standard Maven CI-friendly inheritance: the root takes the modules' own former parent (qbit-build-parent 2.0.0, identical for all four
modules), every module's parent becomes the root (version ${revision}, relativePath ../pom.xml) and the per-module <revision> properties are
removed. Each module's inherited build configuration is unchanged (child -> root -> the same qbit-build-parent); modules still build on their
own through the relative parent. Metadata audit: the root declares Apache-2.0 and base declares it too (unchanged); rdbms, middleware and
github declared no license and inherited qbit-build-parent's AGPL-3.0, so they now state that same license explicitly to keep their published
metadata exactly as before (the repository LICENSE is Apache: whether those three should be Apache is an owner decision, not changed here).
All GAVs, module boundaries, flatten plugin, dependencies, tests and sources are unchanged.
