feat(audit-log): a consistency pass over the list, filters and entry detail - #2453

🟢 Confidence 10/10 · safe to merge. View-only change on top of an already-reviewed head; every kit option it uses resolves, and the tone/baseline claims are the one part no test can pin.
_{no findings · tests covered · risk low}

A consistency pass over the audit log page: one actor marker per row, quieter source and filters, and a rebuilt entry detail (actions beside values, its own Outcome row). Contained to views and the kit, and safe to merge.

• actorCell draws one 16px marker for every actor via the new actorMark, hidden from AT when the type is the text beside it
• identifier in the detail takes an optional pivot action, so copy and Filter wrap as one group
• ResolvedCustomToday emits FocusAuditDateRange, moving focus into the date range popover for Escape
• copyButton gains the icon-2xs size; attributeFilterAction loses its unused icon option
