refactor(ui): centralize muted_style in style::common

Delete the byte-identical 0.68 muted_style copies across 13 window modules and import crate::ui::style::common::muted_style instead. print_all keeps its local name via muted_style as muted so call sites are untouched. Divergent alphas (0.60/0.62/0.65/0.72) and missing_fonts weak.text left alone to avoid visual changes. Net: +13 / -78, no visual change. Verified: cargo check --all-targets clean, cargo test --lib ui::style (3 passed).
