Fix NameError: restore Optional import in uia/patterns.py

ruff's --fix removed Optional from patterns.py imports (F401) after UP007
converted some usages, but Optional["TextRange"] string annotations at
lines 1412/1426 still require it at runtime. Restored the import and
converted the remaining non-string Optional[X] usages (UP045) to X | None.
