fix(F006-W17.6.1): TableActions 收紧间距 + 理顺布局逻辑

用户反馈: 按钮没显示全 + 间距太大不美观

间距收紧:
- el-button text padding 0 8px → 0 4px (默认太松散)
- .rr-table-actions gap 4px → 0 (按钮紧贴)
- ⋯ 触发器 26px → 22px (更小巧)
- 实测: 按钮间距 0px, 按钮到⋯ 间距 2px

布局逻辑理顺:
- 多个 computed (visibleActions/isCollapsing/primaryActions/moreActions)
  → 合并为单一 layout computed ({primary, more})
- 减少中间依赖, 更可靠

Playwright 验证通过 (订单页):
- status=1 行: [详情,付款] + ⋯ (4按钮前2显)
- status=4 行: [详情,退款,打印] (3按钮全显无⋯)
- status≥5 行: [详情,打印] (2按钮无⋯)
