refactor(settings): stage 6.5b sweep ::v2:: prefix out of consumers

Final mechanical pass: replaces every remaining
`fabro_types::settings::v2::*` import path with
`fabro_types::settings::*` (or the appropriate submodule) across 53
files in 10 crates, then deletes the transitional
`pub mod v2 { pub use super::*; }` alias from
`fabro-types/src/settings/mod.rs`.

No functional changes — all touches are `sed s|settings::v2::|settings::|g`
on import statements and fully-qualified type paths. The v2
namespace is now fully gone; the authoritative module path is
`fabro_types::settings::{accessors, cli, duration, features, interp,
model_ref, project, run, server, size, splice_array, tree, version,
workflow}`.

All 3,758 workspace tests pass. `cargo fmt --check --all` and
`cargo clippy --workspace -- -D warnings` are clean.
