fix(v0.40.3): width-independent help-text + fastapi-skip on CI

CI failures on this commit:
- macOS Typer help text wraps `--judge` / `--trace-log` to two lines on
  narrow CI terminals; tests asserted the raw string. Strip whitespace
  before match (mirrors v0.40.2 width-independent fix).
- `fastapi` is not in the base CI deps (only `[serve]` extra); two
  `_create_app` tests ImportError-ed. Skip those tests when fastapi is
  unavailable.
