Fix mypy strict unused-ignore across Python versions

annotationlib was added to stdlib in 3.14; the type: ignore[assignment]
is needed on 3.14 (where mypy knows the module type) but flagged as
unused on 3.12/3.13 (where mypy treats it as Any). Add a per-module
mypy override to suppress warn_unused_ignores for document_base and
restore the original try/except pattern.
