feat(tui): add configurable session_list_limit for session picker

Adds session_list_limit config option to limit sessions displayed in the session list dialog (default: 150).

Limit only applies when not searching; search uses server-side limit of 30.

Remove message_limit as it conflicts with cursor-based pagination (anomalyco#8535) and is now redundant.

Closes anomalyco#6137
