fix(m9/T28b): forward --trigger-kind on alarm-update/script-add/script-update; fix default-selector test

Three dead-code bugs: --trigger-kind was registered but never read or forwarded on the
alarm-update, script-add, and script-update paths. Introduced TriggerConfigJson.InjectAnalysisKind
helper that rewrites any raw --trigger-config JSON blob, writing "analysisKind":"Strict" when
the flag is strict (case-insensitive) and stripping the key for any other value. Wired the
helper into all three handlers alongside the existing alarm-add path (which already used
AlarmTriggerConfigJson.Build). Added 6 unit tests for the new helper in TemplateTriggerKindTests.

Also fixed a false-positive bUnit test (AlarmTriggerEditor_Expression_NoAnalysisKindInConfig_
SelectorDefaultsAdvisory) that passed because "Advisory" appeared anywhere in the HTML; now
asserts select.GetAttribute("value") == "Advisory". Added the missing equivalent test for
ScriptTriggerEditor (ScriptTriggerEditor_Expression_NoAnalysisKindInConfig_SelectorDefaultsAdvisory).
