Five more reads: the catalog, the knowledge base, a client's balance and overview, the agent's setup

POST /api/v1/reads/{id} answers five more declared reads: search the published catalog, search the knowledge base, how much one client owes, where one client stands (open invoices and the channels you talked on, never what was said) and how the sales agent is configured. Same rules as the first nine: OAuth only, the person's role, a workspace switch off by default. The MCP server lists them as read-only tools, and @vorluno/niiko-sdk, niiko and niiko-cli 0.4.0 add one method each.
