Two macOS-only cabana fixes:
- signalview.h: rename the SignalView::setModel parameter that shadowed
the `model` member. Newer clang (Apple clang 21) folds
"parameter shadows a field" into plain -Wshadow, so with -Werror this
breaks the macOS build. Older clang (CI's image) only flags it under
-Wshadow-all, which is why CI stays green. The rename is clean under
any -Wshadow level and gcc.
- devicestream.cc: the --zmq bridge path had a stale `openpilot/`
segment (`../../openpilot/cereal/messaging/bridge`), a monorepo-layout
leftover that resolved to a non-existent triple-`openpilot` path, so
the bridge failed to exec and live streaming was broken. Drop it to
`../../cereal/messaging/bridge`.
