Fix missing YAML-to-SWG mappings for MeshCore plugins

The MeshCore mod plugin references SWGMeshcoreModActions in
meshcoremod.cpp, but MeshcoreMod.yaml had no MeshcoreModActions
section. When swagger files are regenerated, the auto-generated
SWGChannelActions.h/cpp lose the meshcore_mod_actions member and
accessors, which would break compilation of meshcoremod.cpp.

Changes across five files:

- MeshcoreMod.yaml: add MeshcoreModActions definition (sendNow
  field, matching existing hand-authored SWGMeshcoreModActions)
- ChannelActions.yaml: add MeshcoreModActions  pointing to
  the new section
- SWGModelFactory.h: add #include and create() registration
  block for SWGMeshcoreModActions (was missing despite
  SWGMeshcoreModSettings/MeshcoreDemod* being registered)
- webapirequestmapper.cpp: add channelActionsKey routing branch
  for MeshcoreModActions (was completely absent)
- webapiutils.cpp: add m_channelURIToSettingsKey and
  m_channelTypeToSettingsKey entries for both MeshcoreDemod and
  MeshcoreMod (were missing, unlike ChirpChat and Meshtastic
  which have entries for their channel types)
