feat(audit-log): icons for actions, actors, surfaces and outcomes - #2433

🟢 Confidence 10/10 · safe to merge. Presentational change confined to the audit-log view and two optional kit props; the kickoff's "changed since" list named unrelated files, so pr_changed_files' five files were the review.

Adds glyphs across the audit log — row actions, actor/source/outcome badges, filters, entry detail and day headings — from a verb table the types keep exhaustive, and rebalances the row columns to make room. View-only; safe to merge.

• auditActionIcon picks a glyph from the action's verb, a bolt for an unknown one
• eyebrow and attributeFilterAction gained an optional icon
• The resource column shares the row's spare width with the action
• The source column moves from @xl to @2xl, the lookup field takes leftover space
