feat: locale-aware notification templates + UX improvements

- Add locale support to notification templates (matching command template pattern): TemplateSlot now has locale field with (config_id, slot_name, locale) uniqueness, nested API format {slot: {locale: template}} - Migration merges separate EN/RU system configs into unified per-provider configs; seeds create one config per provider with multi-locale slots - Locale-aware dispatch with EN fallback in NotificationDispatcher - Frontend locale tabs (EN/RU) on template config editor - Fix tracking config cards not showing default provider icons - Global provider filter, search palette, and various UX polish
