feat(ui-react,console): extract FullUploader from Console into shared…

[luisawatkins]

Extract the full upload tool UI from Storacha Console into the shared UI package and migrate Console to consume the new shared component. The new FullUploader component in @storacha/ui-react is built on the existing headless uploader primitives and preserves current Console behavior.

What’s Included

• Added FullUploader to @storacha/ui-react and exported it:
  • packages/ui/packages/react/src/FullUploader.tsx
  • packages/ui/packages/react/src/index.ts
• Switched Console uploader to use the shared FullUploader:
  • packages/console/src/components/Uploader.tsx
• Preserved behavior for:
  • Single file, directory, and CAR uploads
  • Status-driven UI: progress with shards, success (CID link), and error handling
• Added optional kmsConfig support for space.access.type === 'private'.

API Notes

FullUploader props:

• onUploadComplete?: (props: { file?: File; files?: File[]; dataCID?: AnyLink }) => void
• space?: any
• gatewayURL?: (cid: string) => string
• kmsConfig?: { keyManagerServiceURL: string; keyManagerServiceDID: string; location?: string; keyring?: string; allowInsecureHttp?: boolean }

Defaults:

• Gateway link: https://${cid}.ipfs.w3s.link
• Directory wrapping enabled for single files.

Migration

• Console now imports FullUploader from @storacha/ui-react and passes existing onUploadComplete and space.
• Upload page route remains unchanged and continues to function:
  • packages/console/src/app/space/[did]/upload/page.tsx
