fix(home-assistant): disable deprecated http: config section on ha-dev

HA core has migrated the http: config (server_port, ip_ban_enabled,
login_attempts_threshold, use_x_forwarded_for, trusted_proxies) out of
configuration.yaml, causing "already been migrated and is now being
ignored" warnings. Disable http.enabled by default on home-assistant-dev,
mark the section deprecated in both charts, and document removal planned
for appVersion 2027.7.
