[WIKI-419] chore: new asset duplicate endpoint added

[aaryan610]

Description

This PR introduces a new endpoint to duplicate assets and attach them to an entiyt without the need to re-upload them.

Type of Change

• [x] Improvement (change that would cause existing functionality to not work as expected)

Summary by CodeRabbit

• New Features

  • Duplicate file assets via API and receive a new asset ID.
  • Per-asset rate limiting to reduce excessive duplicate requests.
  • Editor support for duplicating embedded assets (rich text/images) with retry UI on failure.
  • Paste handling now processes and deduplicates embedded assets; editor paste sanitization that removed img tags has been removed.

• Bug Fixes

  • None.

Walkthrough

Adds a workspace-scoped POST endpoint to duplicate uploaded assets (per-asset throttled), server logic to copy storage and create a new FileAsset, client-side service/store/hook wiring to call it, editor file-handler duplicate support, paste-time duplication handlers, and custom-image duplication lifecycle and UI retry controls.

Changes

Cohort / File(s)	Change Summary
API route & export apps/api/plane/app/urls/asset.py, apps/api/plane/app/views/__init__.py	Register DuplicateAssetEndpoint route at assets/v2/workspaces/<str:slug>/duplicate-assets/<uuid:asset_id>/ and export the endpoint from views.
API implementation & throttling apps/api/plane/app/views/asset/v2.py, apps/api/plane/throttles/asset.py, apps/api/plane/settings/common.py	Add DuplicateAssetEndpoint (POST) that validates inputs, maps entity context to FK, copies storage object to a new key, creates a new FileAsset (uploaded=true) and returns new asset id; add AssetRateThrottle keyed by asset_id and register asset_id = 5/minute (and anon = 30/minute).
Web client — service & store apps/web/core/services/file.service.ts, apps/web/core/store/editor/asset.store.ts, apps/web/core/hooks/store/use-editor-asset	Add fileService.duplicateAsset(...); expose duplicateEditorAsset in store/hook that calls the service and returns { asset_id }.
Web UI integrations apps/web/core/components/**, apps/web/core/components/editor/rich-text/description-input/root.tsx, apps/web/core/components/inbox/modals/create-modal/issue-description.tsx, apps/web/core/components/issues/issue-detail/issue-activity/helper.tsx, apps/web/core/components/issues/issue-modal/components/description-editor.tsx, apps/web/app/.../page.tsx	Wire duplicateEditorAsset into editor/file handlers and RichTextEditor via new duplicateFile prop; handlers call duplication with workspace/project/entity params, propagate returned asset id, and surface consistent error messages on failure.
Editor paste plugin & helpers packages/editor/src/ce/helpers/asset-duplication.ts, packages/editor/src/core/plugins/paste-asset.ts, packages/editor/src/core/extensions/utility.ts, packages/editor/src/core/props.ts	Add asset-duplication handlers (image handler injecting new UUID and STATUS=DUPLICATING), add PasteAssetPlugin to process pasted HTML via handlers and re-dispatch modified paste, register plugin in utility extension, and remove prior transformPastedHTML hook.
Custom-image types, utils, extension packages/editor/src/core/extensions/custom-image/types.ts, .../utils.ts, .../extension.tsx	Add ECustomImageStatus enum (PENDING, UPLOADING, UPLOADED, DUPLICATING, DUPLICATION_FAILED), include STATUS in defaults, add helpers (isImageDuplicating, hasImageDuplicationFailed, etc.), and expose optional duplicateImage option from fileHandler.
Custom-image components (node-view / uploader / block) packages/editor/src/core/extensions/custom-image/components/node-view.tsx, .../uploader.tsx, .../block.tsx	Integrate duplication lifecycle: node-view triggers duplicateImage when status is DUPLICATING and updates attrs or sets DUPLICATION_FAILED; uploader accepts hasDuplicationFailed, shows Retry UI and blocks picker while failed; block component adjusts loader/toolbar/resizer visibility during duplication.
Editor types & props packages/editor/src/core/types/config.ts, packages/editor/src/core/props.ts, packages/editor/src/core/extensions/utility.ts, packages/editor/src/core/plugins/paste-asset.ts	Add duplicate(assetId: string) => Promise<string> to TFileHandler; remove transformPastedHTML from CoreEditorProps; register PasteAssetPlugin() in utility plugins.
Site app fallback apps/space/helpers/editor.helper.ts	Add a no-op duplicate(assetId) handler returning the same id as fallback (marked unsupported for sites/space).

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

• Areas needing extra attention:
  • Storage copy semantics and chosen destination key naming in DuplicateAssetEndpoint.post.
  • Correctness of entity-type → FK mapping in get_entity_id_field.
  • Throttle key logic in AssetRateThrottle.get_cache_key and matching DEFAULT_THROTTLE_RATES key.
  • Paste plugin HTML mutation, idempotency marking (data-uploaded) and re-dispatch behavior.
  • Concurrency guards and retry transitions in custom-image node-view/uploader (DUPLICATING → UPLOADED / DUPLICATION_FAILED).
  • Client-side error propagation and consistent UI messages across duplicate flows.

Poem

I’m a rabbit with a tiny hat,
I clone pixels where they sat.
Keys get twins and paste gets wise,
Throttle hums and small retries.
Hop again — the duplicate flies! 🐇✨
