* fix(storage): scope S3 upload keys by workspace

Upload keys now use `workspaces/{workspace_id}/{uuid}.{ext}` instead of
flat `{uuid}.{ext}`, isolating file storage per workspace. Files uploaded
without workspace context (e.g. avatars) keep the flat key structure.

* fix(storage): scope user uploads under users/{user_id}/ prefix

Non-workspace uploads (avatars, profile images) now use
`users/{user_id}/{uuid}.{ext}` instead of flat `{uuid}.{ext}`,
matching the workspace-scoped pattern from the previous commit.

* fix(storage): fix LocalStorage for nested key paths

- Add MkdirAll before WriteFile to create intermediate directories
  for workspace/user-scoped keys
- Fix KeyFromURL to preserve full path after /uploads/ prefix instead
  of stripping to just the filename
- Update tests to match new behavior

* fix(upload): validate ownership before writing to storage

Move Storage.Upload after issue_id/comment_id ownership validation
to prevent orphaned files in S3 when validation fails. Previously,
the file was uploaded first and validation happened after, leaving
files in workspace-scoped S3 prefixes even on rejected requests.

* fix(upload): restore workspace membership check before upload

The membership check was accidentally removed during the upload
reordering refactor. Without it, any authenticated user could upload
files to any workspace by setting the X-Workspace-ID header.

Also restores the comment explaining the 200-on-DB-error behavior.
