feat(ui/templates): structured trigger editor for template scripts
The script add/edit modal exposed a script's trigger as two raw free-text inputs — a type string and hand-written config JSON — with no validation and no parity with the alarm trigger UI. Replace them with a ScriptTriggerEditor component (mirroring AlarmTriggerEditor): a trigger-type dropdown plus type-specific panels for Interval, ValueChange, Conditional, and Call, a grouped attribute picker, and an auto-generated hint. A ScriptTriggerConfigCodec round-trips the TriggerConfiguration JSON the site runtime's ScriptActor consumes, tolerant of legacy keys; an unrecognized stored type is preserved untouched in a read-only panel.
