chore(warnings): silence the four pre-existing script warnings the creation screen surfaced

Not errors and not regressions — Godot printed them on every script reload
and they predate M4-b. Cleared so a real warning is not lost in the noise:

- Redundant `const ContentDB`/`const NewGame` preloads that shadowed their
  own `class_name` globals (character_creation.gd, creation_draft.gd) — the
  class is already global, so the const bought nothing.
- Two `log` locals shadowing the built-in `log()` — renamed to `out`
  (canon_log.from_dict) and `canon` (NewGame.construct); the "log" dict KEY
  is the public contract and is unchanged.
- currency.format's copper->denomination division is integer BY DESIGN (the
  remainder is carried, not lost) — annotated `@warning_ignore` to say so.

319 client tests green; headless parse reports none of the four sites.
