Bundle a local json-digger copy to support Vaadin 25.2

[paodb]

Fix Vaadin 25.2 compatibility (memoize is not a function, #97)

json-digger@2.0.2's published bundle is a broken webpack dev build (its source has a stray require("webpack")) that fails under Vaadin 25's Vite build. Since there's no upstream fix and the JSONDigger global is still required, this replaces the bundle import with a local corrected copy of its source (only the stray require removed, export converted to ESM; MIT header preserved). Works on Vaadin 14, 23, 24 and 25.

Close #97

The pull request vendors JSONDigger as a local ES module, updates fc-orgchart.js to import it locally, excludes the vendored source from license processing, adjusts demo JAR contents, sets the demo theme to LUMO, and updates the Vaadin 25 profile to 25.2.3.

JSONDigger vendoring and runtime integration

Layer / File(s)	Summary
Vendored JSONDigger implementation src/main/resources/META-INF/frontend/json-digger.js	Adds JSON tree lookup, matching, navigation, mutation, update, removal, validation, and default ES-module export behavior.
Runtime JSONDigger source selection src/main/resources/META-INF/frontend/fc-orgchart.js, pom.xml	Switches the runtime import to the local module and excludes the vendored MIT source from license processing.
Maven demo and Vaadin configuration pom.xml, src/test/resources/META-INF/dynamic-theme.properties	Excludes the dynamic theme properties from the demo test JAR, sets the theme to LUMO, and updates Vaadin to 25.2.3.
