[1.x] Pre-release tidy-up (#1010)

Changes:
* no source changes
* (build) expel all versions from child modules: they must be all top level depMgmt or pluginMgmt
* (build) Top POM contains GAVs while child modules GA+scope. This tremendously simplifies maintenance.
* (javadoc) fix Javadoc errors

Updates:
* use latest Maven 3.9.8-SNAPSHOT (TS locked version, controlled deploy by me)
* AssertJ 3.26.0
* Takari Smart Builder 0.6.6
* Sisu 0.9.0.M3
* maven wrapper 3.3.2 w/ scripts

This brings mvnd-1.x in "releasable" state (once Maven 3.9.8 is out).
