fix(data): populate aiConversationCount from conversations.db instead of returning 0

The /_web/sessions route never called getAIChatCountsBySession() to
enrich session DTOs, leaving aiConversationCount always 0 in the
data management UI. Use the existing enrichSession callback and
AIChatManager to fill real counts for both list and detail endpoints.
