Removes Instagram permissions from the Facebook Messenger inbox setup
flow to avoid blocking Meta App Review for Messenger-only apps.
Meta rejects or stalls Messenger-only app reviews when the OAuth flow
requests unrelated Instagram permissions such as `instagram_basic` and
`instagram_manage_messages`. This blocks approval for Messenger
permissions like `human_agent`, even when the user only wants to
configure a Facebook Messenger inbox.
New Facebook Messenger inbox setup now requests only the Page and
Messenger permissions required for Messenger. Existing Facebook
Messenger inboxes that already have Instagram details continue to
request Instagram permissions during reauthorization, preserving support
for the legacy combined Facebook/Instagram inbox flow.
Going forward, new Instagram setups should use the dedicated Instagram
channel inbox instead of being bundled into the Messenger setup flow.
Closes#13860
## How to test
1. Go to Settings → Inboxes → Add Inbox → Facebook Messenger.
2. Click Login with Facebook.
3. Verify the OAuth scope does not include `instagram_basic` or
`instagram_manage_messages`.
4. Reauthorize an existing Facebook Messenger inbox with `instagram_id`
present.
5. Verify the reauth scope still includes `instagram_basic` and
`instagram_manage_messages`.

Extracts the Meta JS SDK logic for the WhatsApp embedded-signup and
Facebook Page connect flows out of their settings components into two
reusable composables. No behavior change — the settings inbox-creation
flows work exactly as before; this just makes the SDK orchestration
reusable (an upcoming onboarding PR consumes them) and adds unit
coverage.
## What changed
- `useWhatsappEmbeddedSignup` — owns the embedded-signup popup (SDK
load, FB.login, and the auth-code / postMessage race).
`WhatsappEmbeddedSignup.vue` now consumes it.
- `useFacebookPageConnect` — owns FB.login (page scopes) + page fetch,
with SDK preload split from login so the popup opens within the click's
activation window. `Facebook.vue` now consumes it.
- Adds unit specs for both composables.
