feat: replace all select dropdowns with IconGridSelect, fix EN template seed

Shared grid-items.ts with reusable item definitions for: sort by/order,
album mode, asset type, memory source, locale, response mode, event type
filter, chat action, preview target type, provider type.

Replaced selects on:
- Dashboard: event type, provider, sort (compact mode — auto-width)
- Tracking configs: sort by/order, album modes, asset types, memory source
- Command configs: locale, response mode, provider type
- Targets: chat action
- Template configs: preview target type, provider type
- Command template configs: provider type
- Providers: type selector (read-only during edit)

IconGridSelect: added compact prop for inline filter bars (auto-width,
smaller padding, shows icon + label text).

Backend: template seed now re-creates deleted system templates on startup
using raw SQL to handle legacy NOT NULL columns.

Added i18n: trackingConfig.providerType, trackingConfig.sortRandom
Added provider_type badge to tracking config cards.
