Add a 'Copy from existing' option to the New Canvas modal. It lists every
canvas with node/group/text counts; picking one deep-copies its nodes, edges,
parent/child links and canvas state (viewport, custom style, floor plan) into
a fresh design.
Backend: POST /designs/{source_id}/copy remaps node ids, re-points edges and
parent links, and clones canvas state; GET /designs now returns per-design
counts for the picker. Standalone mode clones the localStorage canvas.
Closes#216
ha-relevant: maybe
- Resize handles only render when the plan is selected (click to select,
click outside to deselect); previously always shown when unlocked.
- Double-clicking an unlocked plan opens the canvas edit modal (via a
floorMapEditNonce signal the Sidebar watches).
- Floor plan always sits at the bottom of the canvas (z-index -1), behind
nodes and edges, locked or not.
- Remount the edit modal on every open (key bump) so it re-seeds from the
current floor plan; fixes Save clobbering a canvas-side resize/move with
stale modal dimensions.
- Drop the no-op history snapshot on floor-plan edits (floorMap isn't part
of undo history).
- Render floor plan inside React Flow ViewportPortal so it pans/zooms with
nodes (was screen-fixed, desynced on pan/zoom); zoom-stable resize handles.
- Move floor plan config from the left panel into the canvas (design) edit
modal; attach per-design and fix cross-design bleed on load.
- Store images via a new generic backend media endpoint (POST/GET/DELETE
/api/v1/media) on disk under <data_dir>/uploads, not base64 in the canvas.
- Disable floor plans in standalone mode (no backend to upload/serve); drop
base64 localStorage persistence. See ADR-001 in CLAUDE.md.
- Tests: backend media route, DesignModal floor plan + upload, store floorMap.

Make designs (canvases) fully user-manageable: create with a chosen name
and icon, rename, change icon, and delete. Replaces the hardcoded
"New Electrical Design" button with a generic "New Canvas" flow.
- Add Design.icon column + migration that backfills legacy rows
(electrical -> zap, others -> dashboard)
- DesignModal: name input + curated lucide icon picker (create + edit)
- Sidebar switcher gains per-canvas edit/delete; delete guards the last
canvas and confirms
- designStore: addDesign/updateDesign/removeDesign with active reassignment
- Fix data loss on design switch: abort load when the save fails and keep
unsaved edits; skip the save-old step when the previous canvas was deleted
- designsApi create/update carry icon; design_type kept for back-compat
Tests: backend design CRUD (icon + cascade + last-canvas guard), designStore
actions, designIcons resolver, DesignModal create/edit/validation.
