Eric Traut d7104e268b Fall back to summary history for read-only conversations (#45980) ...

## Why

History paging failures can prevent the TUI from opening a conversation that is already open elsewhere, even when its prompts and final replies are available through turn summaries.

## What changed

- When paginated read-only history loading fails, request the latest 100 turns from `thread/turns/list` with `itemsView: summary` and display them in chronological order.
- Clear history pagination state and show a notice that intermediate messages and tool activity are unavailable. Surface the notice during startup, session selection, and command center selection.
- Show a concise retry message when the command center cannot load the conversation, preserving the current conversation.

## Testing

Extend read-only history tests to cover summary recovery, the 100-turn limit and ordering, the user notice, and preservation of the current conversation when both history loading methods fail.
