Subject: feat: major editor overhaul (assets, properties, timeline, fonts)
 (#709)

* feat: major editor overhaul (assets, properties, timeline, fonts)

Refactor editor core systems to standardize UI architecture and improve performance.

Assets & Properties:
- Replace monolithic property items with composable `Section` architecture.
- Add specialized sections for Transform, Blending, and Text.
- Implement `NumberField` with scrubbing and math evaluation.
- Add new ColorPicker with EyeDropper and multiple format support.
- Standardize asset panels using new `PanelView` layout.

Fonts & Stickers:
- Implement custom font atlas/sprite system for high-performance previews.
- Add virtualized FontPicker with search and favorites.
- Refactor stickers to use a provider-based architecture (icons, emoji, flags, shapes).
- Standardize sticker IDs to `provider:value` format.

Timeline & Interaction:
- Convert bookmarks to rich objects with notes, colors, and duration.
- Refactor drag-and-drop to use Command pattern (enabling proper undo/redo).
- Add Shift modifier to disable snapping during moves/resizes.
- Add new overlays for layout guides and text editing.

Renderer:
- Add support for multi-line text, custom line-height, and letter-spacing.
- Implement global composite operation (blend modes).
- Update sticker node to resolve dynamic provider IDs.

Infrastructure:
- Add storage migrations (v3->v6) for text weights, sticker IDs, and bookmarks.
- Update global styles and core UI components (Button, Input, Popover).

* add ts-nocheck directive to settings-legacy.tsx to suppress TypeScript errors

* fix: correct global composite operation assignment in TextNode to ensure proper blend mode handling

* deleted shadcn components with errors

* formatting

* fix linter issues

* migrate from next middleware to proxy

* add missing component back

* add breadcrumb back

* chore: add @radix-ui/react-primitive deps

* chore: more deps

* chore: add missing env vars to bun-ci

* next env
