feat(routing): independent per-family MeshCore channel (#9)
Add meshcore_channel (Optional, default None) to each notification family
toggle, routed independently of the Meshtastic broadcast_channel. On a
broadcast the Meshtastic child uses broadcast_channel and the MeshCore
child uses meshcore_channel; an unset meshcore_channel means the family
does NOT broadcast on MeshCore (no default, no parallel to Meshtastic).
Additive; Meshtastic-only behavior unchanged.

"""Per-family MeshCore channel routing tests.
Tests the independent meshcore_channel field on NotificationToggle /
NotificationRuleConfig and how it threads through the notification pipeline.
Covers:
1. Config round-trip: meshcore_channel serialises/deserialises correctly.
2. _toggle_to_rule: carries meshcore_channel from toggle into rule.
3. MeshBroadcastChannel: both channel and meshcore_channel passed to connector.
4. meshcore_channel=None: connector receives meshcore_channel=None (transport
layer is responsible for the skip; channel-level just passes it through).
5. transport=meshtastic (default): connector called with just channel; no
breakage from the new optional meshcore_channel kwarg.
6. End-to-end via Dispatcher with mock children that track per-transport calls.
