[BUG] iOS Code tab: completed/idle sessions show gray status dot instead of green

Description

In the Claude Code iOS mobile app, on the Code tab's Sessions list, completed/idle sessions used to show a green status dot. As of today (2026-09-04), they render as a plain gray dot instead.

Screenshot

Sessions list shows:

• VM111-f44-vpn-claude — orange dot, "Waiting for you" (this one looks correct/expected — orange = needs input)
• client-upgrade-reef-squid... — gray dot, last activity "6m"
• QE_Tracker — gray dot, last activity "15m"

The latter two are finished/idle sessions that previously showed green and now show gray.

Expected behavior

Idle/completed sessions with no pending action should show their usual green status dot, distinct from gray (offline/no-status) and orange (waiting for input).

Actual behavior

Idle/completed sessions render with a gray dot, visually indistinguishable from an offline/disconnected state.

Environment

• Platform: iOS (iPhone), Claude Code mobile app, Code tab
• Noticed: 2026-09-04 (today) — exact app version not captured; reporter did not have it on hand at report time
• Reproducibility: consistently observed across multiple sessions in the list at time of report

Additional context

Searched existing issues for green, iPhone, iOS, gray dot, mobile status color, finished session indicator, etc. — found related-but-distinct reports (e.g. stale/stuck green indicators going the opposite direction, or desktop/VS Code session-list color issues), but no existing report matching this specific gray-instead-of-green regression on the iOS Code tab session list.
