feat: add audit/activity log view with timeline and event filtering (#17)

Add a dedicated /audit route displaying a chronological timeline of
orchestration events (state transitions, tool invocations, errors,
messages) grouped by session. Includes session selector, event type
filtering, URL deep-linking via ?session=id, and audit event capture
during chat streaming.
