fix(whatsapp): route WHATSAPP_* env reads through secret scope for multiplex profiles

Fix #75349 Root cause: Under multiplex_profiles, secondary profiles run inside _profile_runtime_scope which installs a per-profile secret scope via set_secret_scope. The WhatsApp adapter (and the shared WhatsAppBehaviorMixin + Cloud API adapter) read WHATSAPP_MODE, WHATSAPP_DM_POLICY, etc. via raw os.getenv(), bypassing the secret scope. Since os.environ doesn't contain secondary profile .env values, the bridge silently falls back to 'self-chat' and rejects all inbound messages with self_chat_mode_rejects_non_self. Fix: - Add _wenv() helper in adapter.py that reads WHATSAPP_* vars through get_secret() (agent.secret_scope), which honors the active scope. - Replace all os.getenv('WHATSAPP_*') calls in adapter.py, whatsapp_common.py, and whatsapp_cloud.py with get_secret()-based equivalents. - Inject resolved WHATSAPP_* values into the bridge subprocess environment so the Node.js bridge (which reads process.env) sees the profile's own configuration. Changes: - plugins/platforms/whatsapp/adapter.py: 37 lines (+ helper, bridge_env injection, 2 os.getenv→_wenv) - gateway/platforms/whatsapp_common.py: 13 lines (6 os.getenv→_get_wsecret) - gateway/platforms/whatsapp_cloud.py: 21 lines (9 os.getenv→_get_wsecret) - New regression test: 6 test cases covering scope isolation, fallback, and cross-profile non-leakage.
