Retire the deprecated compactLayout alias for highlightFields (framework#2536, closes the ADR-0085 deprecation window).

• ObjectSchema no longer declares compactLayout: create() rejects it like any unknown key; lenient parse() strips it (no silent aliasing).
• The parse-time alias AND the highlightFields → compactLayout back-fill transition mirror are removed from normalizeSemanticRoleAliases. Served metadata now carries the canonical key only.
• All remaining first-party authors (27 system objects across plugin-audit / approvals / security / sharing / webhooks / service-storage / automation / messaging / realtime — missed by the #2521 sweep, caught by the type gate) renamed to highlightFields.
• The downstream smoke pin moves to hotcrm v1.2.2 (hotcrm#424: same rename + deps ^11.7.0).
• Consumers were switched in objectui#2168 and shipped via the console pin bump (#2526); this closes the window scheduled there. The dogfood mirror assertion (#2528) flips to compactLayout: undefined in this same change, per the plan it carried.

Version note: minor, not major — the key was deprecated-with-alias for a full release window, all first-party consumers/authors are migrated, and the spec api-surface gate reports no export changes (same documented-exception path as the ADR-0085 removals in 11.7.0). External metadata still authoring compactLayout will now fail create() loudly with the standard unknown-key error naming the key.
