feat: IconGridSelect, CrossLink, SearchPalette components + entity crosslinks

New components:
- IconGridSelect: Visual grid selector replacing <select> dropdowns,
  with icon + label cells, fixed-position popup, smart placement
- CrossLink: Inline clickable badge for cross-entity navigation,
  hover highlights primary, used on entity cards
- SearchPalette: Ctrl+K global command palette, searches all entity
  types via cached data, grouped results, keyboard navigation

Integration:
- Targets: type selector uses IconGridSelect (4-column grid with icons)
- Targets: bot crosslink on telegram/email/matrix target cards
- Command Trackers: provider and config badges → CrossLinks
- Command Trackers: listener bot name → CrossLink
- Command Configs: template config shown as CrossLink on card
- Notification Trackers: provider CrossLink added to card
- Layout: SearchPalette mounted globally

Infrastructure:
- Added CommandConfig, CommandTemplateConfig, CommandTracker types
- Added notificationTrackersCache, commandTrackersCache to caches
- Added allCaches map and fetchAllCaches() for search palette
- Added searchPalette i18n keys (EN/RU)
