feat: introduce "changed at" field (#251), closes #233

- create new `changedAt` field on notes and tags
- the field differentiates content-editing update timestamps (`changedAt`) from all database writes to the records (`updatedAt`)
- the UI and sorting in the UI now focus on or default to `changedAt`
- generated code for GraphQL typings has changed settings
