fix(deploy): address M2.1 review nits — comparer consistency + comments (#22)

- connection-name capable-set comparer kept as StringComparer.Ordinal:
  FlatteningService and SemanticValidator use all-ordinal name-keyed
  dictionaries throughout; OrdinalIgnoreCase would be inconsistent with
  the rest of the binding-resolution path — added comment documenting this
- IsAlarmCapable protocol-match confirmed consistent with DataConnectionFactory
  (both OrdinalIgnoreCase); added case-insensitive InlineData variants
  (OPCUA, opcua, mxgateway, MXGATEWAY) to lock the contract
- clarified FlatteningPipeline comment: "filters connections by alarm-capable
  protocol, then collects their names" (was "maps from the protocol string")
- added DataConnectionLayer/DataConnectionFactory.cs path reference to
  AlarmCapableProtocols sync-risk comment
