fix(types): resolve 4 pre-existing vue-tsc errors

- EventMetricCards: type navigateTo's routeName as the literal union
  of the two routes it actually targets (events-id-persons,
  events-id-sections) so the typed router accepts it.
- CreateTimeSlotDialog: type the form ref explicitly so person_type
  is PersonType rather than being inferred as string.
- @layouts/types.ts: relax LayoutConfig.app.title from Lowercase<string>
  to string. The lowercase constraint was a compile-time namespacing
  convention in the Vuexy template with zero runtime effect;
  relaxing it lets the branded "Crewli" title satisfy the type.
