fix: correct w:mex QueryIds and response fields for newsletter operations

Reverse-engineered from WA Web JS bundle and live CDP interception.
All QueryIds and XWAPaths were wrong; mute/unmute also had wrong variables structure.

- FOLLOW QueryId: 7871414976211147 → 24404358912487870
- UNFOLLOW QueryId: 7238632346214362 → 9767147403369991
- MUTE QueryId: 29766401636284406 → 31938993655691868
- UNMUTE QueryId: 9864994326891137 → 31938993655691868 (same mutation as MUTE)
- xwa2_newsletter_follow: 'xwa2_newsletter_follow' → 'xwa2_newsletter_join_v2'
- xwa2_newsletter_unfollow: 'xwa2_newsletter_unfollow' → 'xwa2_newsletter_leave_v2'
- xwa2_newsletter_mute_v2: 'xwa2_newsletter_mute_v2' → 'xwa2_newsletter_update_user_setting'
- xwa2_newsletter_unmute_v2: 'xwa2_newsletter_unmute_v2' → 'xwa2_newsletter_update_user_setting'
- newsletterMute/Unmute variables: flat {newsletter_id} → {input: {newsletter_id, type, value}}

Fixes #2346
