feat: activity-based worklog suggestions (Step 16)

- Suggestion struct with nodeId, nodeTitle, summary, suggestedMin
- GetSuggestions binding: analyzes today's activity events, groups by
  node, skips nodes with existing today's worklog, generates summary
- AcceptSuggestion binding: creates worklog entry from suggestion
- HasTodayEntries helper on worklog.Service
- Suggestions panel in Worklog tab with Apply button
- i18n: worklog.suggestions / worklog.apply (ru + en)
