feat(files): allow image uploads in workspace files

[waleedlatif1]

Summary

• workspace Files upload was rejecting all images (PNG, JPG, etc.) because the accept attribute had no image extensions, even though the backend accepts any file type
• added SUPPORTED_IMAGE_EXTENSIONS (png, jpg, jpeg, gif, webp, svg, bmp, tif, tiff, heic, heif, avif, ico) and included it in the workspace files picker
• consolidated the duplicate local image extension list previously used by CHAT_ACCEPT_ATTRIBUTE

PR Summary

Low Risk
Low risk UI/validation-list change that only expands allowed file extensions and labels image MIME types; main risk is inadvertently allowing unexpected image formats in the picker.

Overview
Workspace Files uploads now allow common image formats by adding SUPPORTED_IMAGE_EXTENSIONS to the file picker’s accepted extension list and labeling image/* MIME types as "Image" in the table.

Upload validation constants were consolidated by promoting the image extension list into validation.ts and reusing it for CHAT_ACCEPT_ATTRIBUTE, while also expanding supported image MIME types (e.g., TIFF/HEIC/AVIF/ICO).

Greptile Summary

This PR fixes the workspace file picker rejecting image uploads by adding SUPPORTED_IMAGE_EXTENSIONS to the accepted extensions list and folding SupportedImageExtension into the SupportedMediaExtension union. It also consolidates the previously duplicated local image extension list used by CHAT_ACCEPT_ATTRIBUTE and expands SUPPORTED_IMAGE_MIME_TYPES with 7 additional formats (bmp, tiff, heic, heif, avif, x-icon). Both prior P2 concerns — incomplete MIME type coverage and the missing SupportedImageExtension in SupportedMediaExtension — are resolved in this PR.

Confidence Score: 5/5

Safe to merge — the fix is targeted and correct, with no regressions on existing paths.

All findings are P2 style/consistency observations. Both previously flagged P2s (MIME type gaps and missing SupportedImageExtension in the union) are addressed. No P0 or P1 issues found.

apps/sim/lib/uploads/utils/validation.ts — minor consistency gap with SUPPORTED_IMAGE_MIME_TYPES not being exported as a Record like its audio/video counterparts.

Important Files Changed

Filename	Overview
apps/sim/lib/uploads/utils/validation.ts	Adds SUPPORTED_IMAGE_EXTENSIONS constant and SupportedImageExtension type; expands SUPPORTED_IMAGE_MIME_TYPES with 7 new entries; folds SupportedImageExtension into SupportedMediaExtension; removes duplicate local extension list. Minor consistency gap: SUPPORTED_IMAGE_MIME_TYPES is still a private flat array, unlike the exported Record maps for audio and video.
apps/sim/app/workspace/[workspaceId]/files/files.tsx	Imports and spreads SUPPORTED_IMAGE_EXTENSIONS into the workspace file picker's SUPPORTED_EXTENSIONS array, and adds an image/ MIME-type branch to formatFileType. Changes are straightforward and correct.

Image files hidden when any type filter active

Medium Severity

Now that images can be uploaded, the type filter logic in filteredFiles silently excludes them whenever any type filter is active. The filter checks for 'document', 'audio', and 'video' but has no 'image' branch, so image files always hit return false. The filter dropdown also lacks an 'image' option, so there's no way for users to filter for or retain images when filtering by type.
