Port icon grid and entity picker patterns from wled-screen-controller.
IconGrid replaces plain <select> elements with visual icon grids for
known item sets (widget type, icon type, healthcheck method, permission
level). EntityPicker replaces search dropdowns with a command-palette
style overlay with keyboard navigation and filtering.
Enhance SearchDialog with keyboard navigation (arrow keys, Enter,
Escape), grouped results with section headers, active highlight,
and a footer with shortcut hints.
Fix all build/type/lint errors, write 60 new tests (175 total),
update seed with new widget types and team board permissions,
install missing svelte-i18n dependency, fix DynamicIcon for Svelte 5.
- Fix $effect orphan error: move $effect calls from store constructors
to initEffects() methods called from component context
- Fix icon rendering: create DynamicIcon component to render Lucide icons
from name strings instead of displaying raw text
- Add /boards/new route for board creation
- Fix seed emails (admin@launcher.local / user@launcher.local) to pass
