channels: add SendAdapter injection + handler test coverage for Test and Send

- Extract SendAdapter interface (SendMessage only) from ChannelAdapter so
  tests can inject a MockSendAdapter without hitting real Telegram/Slack APIs
- Make GetSendAdapter a package-level var (default: real adapters; tests
  override via SetGetSendAdapter from channels/testing.go)
- Wire GetSendAdapter into Manager.SendOutbound (was GetAdapter → ChannelAdapter)
- Add 4 handler tests in handlers/channels_test.go:
    TestChannelHandler_Test_Success         — full send-outbound success path
    TestChannelHandler_Test_ChannelNotFound — loadChannel error → 500
    TestChannelHandler_Send_Success         — budget pass → send → 200
    TestChannelHandler_Send_ChannelNotFound — loadChannel error → 500
