feat(commons): Layer B serializer + validator handle new OPC UA settings
OpcUaEndpointConfigSerializer:
- ToFlatDict emits new scalar keys (DiscardOldest, SubscriptionPriority,
SubscriptionDisplayName, TimestampsToReturn).
- ToFlatDict emits dotted sub-object keys (UserIdentity.TokenType / Username /
Password / CertificatePath / CertificatePassword, Deadband.Type / Value)
when those sub-objects are non-null.
- FromFlatDict reads the same keys back; missing keys preserve POCO defaults.
- Deadband.Value uses InvariantCulture for double parsing/formatting.
OpcUaEndpointConfigValidator:
- SubscriptionDisplayName required (non-empty).
- UserIdentity.UsernamePassword requires Username.
- UserIdentity.X509Certificate requires CertificatePath.
- Deadband.Value must be > 0 when Deadband is set.
- fieldPrefix propagates through sub-object error EntityNames.
Drives the 11 previously-failing tests green; 51/51 in the suite now pass.
