Follow-up to @zoser69's #78111 cherry-pick:
- lift the redirect into _redirect_platform_display_key() and apply it
BEFORE _validate_config_key / type coercion, so the unknown-key hint and
the string-vs-bool coercion both see the canonical path
- widen to the sibling surfaces: config get resolves the canonical key
(previously echoed the dead top-level value — the misleading half of the
report) and config unset removes the canonical leaf
- regression tests: get mirrors gateway resolve_display_setting, unset
removes the redirected leaf, note printed, helper touches ONLY
OVERRIDEABLE_KEYS (connection keys / 4-segment / already-canonical
paths untouched)
- docs: configuration.md per-platform section names the canonical CLI
path and the accepted shorthand
