feat(m9/T28b): trigger analysis-kind selector (UI) + --trigger-kind (CLI)

Surfaces the T28a backend "analysisKind" discriminator in both authoring
surfaces: an Advisory|Strict <select> (id="alarm-trigger-kind" /
"script-trigger-kind") added to the Expression fragment of
AlarmTriggerEditor and ScriptTriggerEditor, and a --trigger-kind option
on template alarm/script add+update in the CLI.

Key/value contract: "analysisKind":"Strict" when strict; key omitted for
Advisory — exactly as ValidationService.IsStrictAnalysis reads it.
Selector only shown for Expression triggers; non-Expression triggers do
not emit the key even if IsStrictAnalysisKind is set on the model.

Both projects build 0 warnings; 101 CentralUI Trigger tests + 33 CLI
Template tests pass.
