Incident History and Audit Log Updates

The incident history is now a timeline that gives you a dense, chronological record of response events, team actions, and the time between them.

• Vertical Event Timeline: Incident history shows as a vertical timeline with one row per event. Each row has a colored marker, a bold action title, the user who triggered the action, and inline details.
• Day Separators and Gaps: A divider row marks the start of each day and shows the weekday. When a minute or more passes between two events, the timeline adds a row such as "5m later" so you can spot pauses during triage.
• Compact Responder Rows: The timeline saves vertical space during large incidents. On-call events show up to three responder avatars, team events show up to two teams, and acknowledgments show as an icon.
• Live Updates: Events that arrive while you have the incident open slide into the timeline.
• Standardized Plain-Text Labels: Incident history, notification logs, integration logs, routing logs, and edit histories now use the same plain-text action labels, which keeps audit trails consistent and easy to read.
