Shared drives in admin panel

[shepilov]

Summary

• allow POST /sharings/drives to create a new shared drive directly
• expose org_drive so clients can distinguish organization "shared drives"
• track who trashed a file or folder via cozyMetadata

Changes

Add org_drive for organization-backed drives

Shared drives created from an organization instance are now marked with the org_drive flag.

This includes:

• a new Instance.IsOrganizationInstance() helper
• org_drive on sharing payloads
• propagation of the flag to clients and recipients

Track trash actors in cozyMetadata

When a file or folder is moved to trash, the stack now stores:

• trashedAt
• trashedBy

trashedBy is typed and currently supports:

• kind: "member"
• kind: "anonymous-share"

For member actors, the payload also includes:

• displayName
• domain

This metadata is resolved in middleware and then written by the files layer, so the metadata is preserved across normal access, shared-drive access, and replication flows.

are you emptying trash* metadata when the user restaure the file?

Once this PR is merged, update this repo please https://github.com/cozy/cozy-doctypes since we're updating a "lot" the io.cozy.files doctype.

nope, it will stay there until it is overwritten during the next "delete".
