refactor(channel-status): drop breadcrumb + subtitle from MonitorHero

The "CHANNEL · STATUS" breadcrumb and the zh/en subtitles above the
window-picker were redundant with the existing "渠道状态" page title
shown in the layout header. Remove the left column and right-align the
7d/15d/30d tabs + overall chip.

Also drop the now-unreferenced channelStatus.hero.* i18n keys from both
locales (grep confirms no remaining usage).

chore: bump version to 0.1.114.31
