+ * ConnectPanel
+ *
+ * The portal is a *management* console — config, billing, usage — but
+ * the assistant itself lives in the customer's messaging app. Nothing
+ * previously told the customer how to actually start talking to the
+ * thing they just provisioned ("Your assistant is ready… now what?").
+ *
+ * This panel closes that gap on the tenant-detail page: for each
+ * enabled channel it shows the concrete first-contact steps, and when
+ * NO channel is enabled it says so explicitly (a running assistant with
+ * no channel is unreachable).
+ *
+ * Once a customer has connected they don't need the steps every visit,
+ * so the panel is dismissible: clicking "I've connected" collapses it
+ * to a slim row and remembers that per-tenant (localStorage). The slim
+ * row keeps a "Show connection details" toggle so it's never lost.
+ * The no-channel warning is NOT dismissible — it's an actionable alert,
+ * not reference material.
+ *
+ * It is intentionally complementary to ChannelUsers below it:
+ *   - ConnectPanel  → "how do *I* reach the assistant"
+ *   - ChannelUsers  → "*who* is allowed to reach it"
