Improved Stripe Settings visibility

Updated Settings > Stripe to include the following fields. This is to support our move to Automated Revenue Sharing.

• Account Email
• Bank Account details
• Payout details

Conversation composer and side panel issues, including assignee dropdown flicker, draft reply state loss, requester lookup and error copy, attachment display, merge suggestions, and conversation identification from inbound SMS.

Sidekick panel regressions so it stays open when expected and no longer auto-opens or closes unexpectedly on refresh or URL-param flows.

Signal scheduling and notification issues, including recurring schedule duplication, mobile transcript layout, invalid SMS handling, holiday deadline display, and fallback routing.

View and list behavior so large-screen scrolling, duplicate rows, pagination, nav resize persistence, and Me assignee filtering work correctly.

Notification and email edge cases, including blocked sender handling, brand-group CC filtering, inbox header alignment, and outbound header size limits.
