test(settings): assert migrated settings display canonical path

Extend the #2730 settings migration harvest with the missing platform-config fallback display assertion from review, and keep the v0.9 execution map/changelog credit current.

Validation: cargo fmt --all -- --check; git diff --check; cargo test -p codewhale-tui --bin codewhale-tui --locked settings_ -- --nocapture; cargo test -p codewhale-tui --bin codewhale-tui --locked display_localizes_header_and_config_file_label -- --nocapture.

Harvested from PR #2730 by @xyuai.

+- `/config` now reports the canonical `~/.codewhale/settings.toml` path for TUI
+  settings while still reading legacy DeepSeek-branded settings fallbacks and
+  migrating them into the CodeWhale home on load.
 - Split `web_run` session/page cache state so cached page reads use shared
   page handles and do not serialize through the mutation path. The harvest also
   adds panic-safe state write-back and serializes cache-mutating unit tests so
