Three issues in the Inbox page:
1. "WhatsApp not connected" banner always showed even when connected.
The connection check queried .from("whatsapp_configs") (plural) but
the actual table is whatsapp_config (singular). Query always returned
no rows, so status was never "connected". Changed to the correct
table name and also switched .single() → .maybeSingle() so a missing
row returns null cleanly instead of throwing PGRST116.
2. The banner overlapped message content — it used absolute positioning
at top-14, left-60, which floated over the thread's header. Restructured
the page layout so the banner is part of the flex column (pushes panels
down) instead of overlapping them.
3. The inbox "kept refreshing every second" — an infinite loop between
MessageThread's fetch and the realtime subscription in the page:
MessageThread useEffect depended on a fetchMessages callback that had
[conversation, onMessagesLoaded] deps. After fetching messages, it
always issued a conversations.unread_count=0 UPDATE. That UPDATE fired
a postgres_changes event. The page's handleConversationEvent received
it and called setActiveConversation({...prev, ...conv}) — creating a
NEW OBJECT REFERENCE for the conversation prop. That changed the
conversation prop passed to MessageThread → fetchMessages changed →
useEffect re-fired → reset unread → fired another realtime event →
loop forever (visible as ~1-2 refreshes per second).
Fix:
- useEffect now depends on conversation?.id only (a stable string),
not the full object reference.
- onMessagesLoaded is read through a ref so it doesn't need to be
a dependency.
- unread_count reset only runs when the conversation actually has
unread messages (avoids UPDATE-thrashing realtime).
