Fix ci-lint: black-format selector.py

black (the version CI's psf/black@stable resolves to) flags three spots
in util/selector.py: the chained .replace() in FormatTransformer.number,
the suppress_zero_inches kwarg in format_length, and the long
`elif key in (...) and hasattr(...)` placement-key tuple in
set_element_value. Reformat all three to black's multi-line style.
Formatting only, no behavioural change (all keys preserved).

This change was made with the assistance of an AI tool.
