chore(changelog): 标记前端已实现 #5131

修改原因：hl-ui changelog loop 需要把前端消费进度回写到契约源，避免领取、实现状态与实际交付脱节。

修改内容：将 frontend_status 与已有 legacy frontend 同步为 implemented，记录负责人 hl-ui-codex，并关联 mmg/hl-ui@ac4d5fd6292b13eb504f5393dfe07781800b9233；发布和验收字段保持不变。

实际验证：回写器已校验目标文件、状态单调性、提交范围和 Front Matter 内容，提交只包含当前 changelog。
