fix: mute records get an unban entry on the restrictions tab

The record list rendered an action only for global ban/suspend rows, so
mute (禁言) rows showed an empty 操作 column with no way to lift them.
- record list: active mute rows now render a 解除禁言 button
- unban view: falls back to the active mute record when no ban/suspend
  exists, with 解除禁言/禁言中 titles (ban > suspend > mute precedence
  preserved); lifting still goes through lift_user_restriction (mute
  included by default)
- contract tests: cover the mute action link and the unban-view fallback
