fix(common): preflight XML doc warnings for strict-gate composition

[ottobolyos]

Summary

Fixes pre-existing XML doc structural defects that surface only when GenerateDocumentationFile=true and TreatWarningsAsErrors=true compose. Two families:

• CS1570 (bare & in /// comments) — escape & to & in 8 sites under libraries/MTConnect.NET-Common/Streams/. Bare & in a doc-comment is interpreted as the start of an XML entity reference; the doc-file build step then reports "badly formed XML in include comment".
• CS1570 (nested <summary> tag) — remove the duplicated <summary> opener in IAdapterApplicationConfiguration.ServiceName, which produces "Expected an end tag for element 'summary'".
• CS1572 + CS1574 (orphan <param name="logger"> + cref ILogger) — three sites in MTConnect.NET-SysML/Xmi/XmiDeserializer.cs carry stale param tags referring to a parameter that no longer exists, and cite a type (ILogger) the project doesn't reference. Drop the lines; the surviving tags cover every real parameter.

These are silent warnings on master today; the build only goes red when a downstream branch flips both gates. Preflighting them here keeps the downstream branch's diff focused on its real change.

Deferred follow-up

Investigation under the strict-gate composition surfaced ~114 additional XML-doc-comment-vs-signature mismatches beyond the structural defects fixed here:

• 104 × CS1573 (parameter has no matching <param> tag)
• 4 × CS1572 (orphan <param> tags at other sites)
• 2 × CS1712 (missing <typeparam>)
• 2 × CS1711 (typeparam for non-existent type parameter)
• 2 × CS1570 (other malformed XML — including one with literal 0x02 in a copy-pasted XML body)

These concentrate in libraries/MTConnect.NET-Common/{Configurations,Agents,Devices}/ (DeviceConfiguration.cs, ConfigurationFileWatcher.cs, MTConnectAgentBroker.cs, IMTConnectAgentBroker.cs, IDevicesDocument.cs). They are pre-existing on master and turn into errors under the same strict gates. Tracking as a follow-up rather than expanding this PR's scope, since the fix is per-signature reconciliation (semantic content review of each <param> block) rather than mechanical escaping.

Closing this — the three doc-comment defects it addressed have all landed in #157 (the VitePress documentation PR) as part of that branch's documentation-gate work, via independent and arguably cleaner fixes:

• the Streams/ summaries were rephrased to "Samples, Events, and Conditions", avoiding the bare ampersand entirely rather than escaping it to &;
• the orphan <param name="logger"> tags on XmiDeserializer were dropped;
• the duplicated <summary> opener on IAdapterApplicationConfiguration.ServiceName was removed.

With #157 carrying equivalent fixes for every item here, this preflight PR is redundant. The broader signature/param-mismatch cleanup noted in the description (the ~114 CS1573/CS1572/CS1711/CS1712 sites) remains worthwhile as a separate future pass.
