fix(step16.1): review fixes — acceptance, filters, sorting, export

- Remove dead acceptSuggestion, unify into refreshAfterSuggestion()
- Journal: nodeID picker, includeChildren only with selected node
- Journal: billable/approximate filters (all/yes/no selects)
- Summary: ByDay sorted by date desc, ByNode by minutes desc
- CSV: proper encoding/csv writer (was manual fmt.Sprintf)
- Markdown: escape pipes and newlines via escMD()
- After suggestion: refresh suggestions + count + worklog + journal
- Add GetNodeTitle binding
- i18n: common.all/no/date/search
