refactor(mac-bar): converge komorebi.rs config text and komorebi_layout.rs onto the Windows source

Schema-text differences only, so that the config types can move into the
core: the macOS KomorebiLayout gets `#[serde(untagged)]` (its Deserialize is
hand-written and nothing in the bar serializes a layout, so no runtime
effect; it only changes the generated schema and the derived Serialize),
`eyre::Result` and `1.0_f32`; KomorebiFocusedContainerConfig::show_icon gets
the Windows `#[deprecated]` and doc (with `#[allow(deprecated)]` at the one
use). The macOS schema view already sets the macOS text of KomorebiLayout
and show_icon back, so komorebi-for-mac/schema.bar.json and
nix/komorebi-bar-options.nix do not change. The coordinator asked to leave
komorebi_layout alone: this was done because the evidence says it is not a
behaviour difference (custom Deserialize, no serialization anywhere in the
macOS bar: `grep to_string|to_value|to_writer` finds none); it is a separate
revision and can be dropped.

Verified: schema harness macOS and Windows byte-identical (3,774 / 9,091
lines); the two komorebi_layout.rs are byte-identical and the config region
of the two komorebi.rs is identical; Windows clippy -D warnings --locked
clean; macOS fake-CC check --locked 0 errors.
