chore(deps): move javax.servlet-api / tomcat-jasper out of root dependencyManagement

Both artifacts are javax-era dependencies consumed only by:
  - easydoc-core    (javax.servlet-api, provided)
  - easydoc-xhtml   (javax.servlet-api, provided)
  - easydoc-jsp     (javax.servlet-api + tomcat-jasper, compile)

The root pom no longer manages them, so downstream projects that use
io.github.easy4j:easydoc as their parent no longer inherit javax-namespace
entries in their dependencyManagement. Each consumer module now declares
its own version explicitly (still single-sourced from the parent's
${servlet-api.version} / ${tomcat-jasper.version} properties).

easydoc-bom was never affected: its dependencyManagement only manages the
10 easydoc-* modules and never re-exported these entries.

Verified: 13-module reactor clean verify green, JaCoCo 90% gate met.
