feat(phase-c): resolve dynamic-dispatch phase-b TODOs

Replace the PHP `call_user_func([$obj, $method], ...)` / `$obj->{'get'.$x}()`
dynamic dispatches (category E) with static Rust dispatch.

- json_config_source: inject the clean-update as a typed
  `FnOnce(&mut JsonManipulator) -> Result<bool>` closure instead of a
  method-name string, dropping the call_user_func_array round-trip through
  PhpMixed args. The auth-config method override moves into the
  add/remove_config_setting closures.
- config_command: dispatch addConfigSetting/addProperty on the concrete
  JsonConfigSource via match.
- locker: select getRequires/getDevRequires and getReplaces/getProvides via
  match on the existing handle getters (previously stubbed to empty Vec).
- create_project_command: reuse the existing get_links_for_type helper.
