feat(configurator): Sub 3 Phase B — part-scoped Process Composer client action + part form Compose button

- Add fp_part_composer_controller with 3 JSON-RPC endpoints:
  /fp/part/composer/state, /fp/part/composer/templates,
  /fp/part/composer/load_template (deep-clones a shared template
  into a part-owned tree inside a cr.savepoint, sets
  fp.part.catalog.default_process_id atomically)
- _clone_subtree copies name/sequence/opt_in_out/treatment_uom plus
  description/notes/icon/color/timing/behaviour/work_center/process_type
  and stamps part_catalog_id + cloned_from_id on every node
- Add fp_part_process_composer OWL client action (JS + XML + SCSS):
  picks template from dropdown, clones, hands off to existing
  fp_recipe_tree_editor via context={recipe_id, part_id}
- Add Process tab on part form with readonly default_process_id
  field and Compose button calling action_open_part_composer
- Register new assets in web.assets_backend, bump configurator
  version to 19.0.11.0.0
