refactor: Restructure project, enhance ActionField and DTOField generation

This commit refactors the project structure by moving generator-related classes
to a new package (`com.sdk.generators.actionmodels`) and standardizing
template directory names (`src/main/resources/templates`).

It introduces new FreeMarker templates (`actionDTO.ftl`, `actionDTO.extend.ftl`)
and corresponding logic in `GeneratorServices.java` to support the generation
of Data Transfer Object (DTO) classes alongside ActionBeans. The changes
also involve enhancements related to `ActionField` and `DTOField` generation.

Updates to `build.gradle.kts`, `plugin.xml`, and Gradle wrapper files
reflect these structural and functional enhancements.
