Change an editable-after-connect setting on a connected number WITHOUT re-pairing. Today the only field is `proxy_url` — the SOCKS5/HTTPS proxy WhatsApp connects through (recommended to avoid IP bans). Owner/admin or the connection owner.
- `account`: which number (id/wa_jid, phone, or label; omit if only one is connected).
- `values`: e.g. { "proxy_url": "socks5://user:pass@host:port" }. An empty string CLEARS the field (e.g. { "proxy_url": "" } connects with no proxy); omit the key to keep the current value.
The new value applies on the next (re)connection; the live session cache is invalidated so the next tool call uses it.
