Register a dedicated `promotion` dashboard panel gated by the existing
invite switches (credits + invite reward + invite registration), and move
the invite card out of the revenue tab so 收益中心 is pure earnings/withdrawal.
- src/User/Center.php: register promotion panel; revenue no longer depends
on invite being on
- inc/helpers/user-center-renderers/profile-promotion.php: new panel body
hosting the existing [data-aksrt-invite] card
- profile-revenue.php: drop the invite section; aksrt-user-center.php: drop
unused show_invite_section context, add promotion to built-in tabs + view map
- repoint invite/promotion deep-link aliases from revenue to promotion across
tab-url builder, tab resolver, runtime tabAliases, urls.php, and the
revenue-JS enqueue gate
- sidebar-nav.php: add 推广中心 service entry; shell.css: entry icon color;
sidebar-creator.php: reword revenue card
- UserRuntime.php: allow promotion in configurable tabs
