feat: journal UX overhaul — picker, export dialog, events, readability

- Sidebar i18n: added missing nav.journal to backend ru.json
- Export: SaveWorklogReport binding with native SaveFileDialog + os.WriteFile
- Filter: better IncludeChildren label with disabled tooltip
- Filter: renamed billable→К оплате, approximate→Тип времени with hints
- worklog_entry_events table (migration 013) linking entries to activity events
- Suggestion: EventIDs + Events details, expandable cards with timestamps
- Journal rows: expandable with details, source, linked events
- Contrast: improved readability for dates, timestamps, hover states
- i18n: added worklog.*, journal.*, suggest.* keys to ru.js/en.js
