feat: UX & notification improvements — icons, events, chat names, link validation, templates

- Show entity icons on all cards with fallback defaults (providers, trackers, targets, bots)
- Enrich EventLog with provider_name, tracker_name, assets_count; add DB migration
- Dashboard events: filtering (type, provider, search), sorting, pagination, dynamic page size
- Friendly chat names on telegram target cards (resolve from TelegramChat table)
- Test message button on bot chat items with locale-aware messages
- Album public link validation on tracker save with auto-create dialog
- Support albums without public links: conditional <a href> in templates
- Fetch shared links during poll, enrich events with public_url/protected_url
- Per-asset public_url in template context ({share_url}/photos/{asset_id})
- Common date/location detection: common_date + common_location context vars
- Dual date formats: date_format (datetime) + date_only_format (date only)
- Template clone button, HTML link rendering in template preview
- Fix Telegram asset download 401: pass x-api-key headers through client
- Fix provider external_url matching for API key scoping
- Fix event timestamp timezone (append Z suffix for UTC)
- Localize event filter controls, test messages (EN/RU)
- Template variable UI helpers updated with all new fields
- CLAUDE.md: template system sync rules documentation
