Services can now carry a brand logo (homarr dashboard-icons) or a generic
lucide icon, the same way nodes already could — closes the request in
discussion #299 where services stand in for docker images.
The add/edit form moves out of the right-hand DetailPanel into a proper
ServiceModal, which gives the icon picker room to breathe and matches how
nodes are edited.
- ServiceModal: name, port, protocol, path, icon; validates the name and
clamps the port, and spreads over the original service on save so fields
it doesn't own (category) survive an edit
- IconPickerPanel: Generic/Brand picker extracted from NodeModal so both
surfaces share one implementation
- ServiceIcon: renders a lucide or brand:<slug> icon in the DetailPanel
badge and on the canvas node, and nothing when the key can't be resolved
- Legacy scanner signature keys (bar-chart-2) still don't resolve to an
icon, but the modal shows them verbatim and preserves them on save
ServiceInfo.icon already existed and the backend stores services as
list[Any], so no schema or migration change.
