feat(cli): add --execution-timeout-seconds + --min-time-between-runs to template script (#54)

Expose TemplateScript.ExecutionTimeoutSeconds and MinTimeBetweenRuns (previously
settable only via Transport bundle import) on the CLI and Central UI authoring surfaces.

- Commons: add additive trailing optionals MinTimeBetweenRuns (TimeSpan?) and
  ExecutionTimeoutSeconds (int?) to Add/UpdateTemplateScriptCommand.
- ManagementActor: thread both new fields into the built TemplateScript on add/update.
- CLI template script add/update: new --min-time-between-runs (duration: ms/s/min,
  bare number = seconds, 0 = unset, mirroring DurationInput) and
  --execution-timeout-seconds (int) flags, with client-side duration validation.
- Central UI TemplateEdit: add an Execution timeout input (seconds) on the script
  trigger tab, mirroring the existing Min-time-between-runs control; null/0 = site default.
- Tests: TemplateScriptTimingTests pins the option surface + duration parsing; updated
  the stale 'no UI control' comment on the TemplateService round-trip test.
