When an agent starts a new conversation, the WhatsApp template picker in
the composer only shows templates that were already loaded into the
frontend store — it doesn't refresh when the composer opens. If a
template sync completed after the store was last populated, the newly
synced template shows up on the inbox's Settings > Templates page (which
always refetches on load) but not in the New Conversation composer,
since that view relied solely on the account-cache-invalidated websocket
event, which doesn't always reach an already-open session in time.
## What changed
- `ComposeConversation.vue` now dispatches a cache-aware `inboxes/get`
refetch every time the composer popover opens, so the WhatsApp template
list is current before an agent picks a template to message a customer.
The refetch checks the account's cache key first and only re-pulls the
full inbox list when it's actually stale, so it stays cheap in the
common case.
## How to reproduce
1. Sync/update WhatsApp templates for an inbox (e.g. via Settings >
Inboxes > [WhatsApp inbox] > Sync Templates).
2. Without reloading the page, open the New Conversation composer for
that inbox and check the WhatsApp template picker — a newly synced
template may be missing until this fix.
