- Box large enum variants in Action, TuiError, CloudWorkerError, and
  IdentityCommands to reduce stack size and eliminate large_enum_variant
  warnings; add manual From impls for boxed error types
- Eliminate unnecessary clones: replace .clone() with as_deref(),
  as_str(), and moves in render loops (header, fuzzy_select_list,
  table_view)
- Replace .to_owned() with .clone() in normalized_filters
  (implicit_clone)
- Use .clone_from() instead of assignment + .clone() (assigning_clones)
- Replace .iter_mut() loops with &mut (explicit_iter_loop)
- Remove redundant closure in table_view .map(|item| item.status())
- Move sources directly in config::ConfigFileBuilder::build() instead of
  borrow + clone
- auth-token: remove unnecessary borrow in _get_auth_data call
