Variable preventBlobCopyOnReadOnlyAccountPluginConst

Prevents Blob/copy operations on read-only target accounts.

Read-Only Account Protection for Blob/copy:

• Validates that the target account's (accountId) isReadOnly property is false
• Blob/copy writes blobs to the target account, requiring write access
• The source account (fromAccountId) only needs read access
• Attempting to copy to a read-only account would fail with an accountReadOnly error

This validator catches the error client-side before making a server request, providing immediate feedback when attempting to copy blobs to read-only accounts.

Common read-only scenarios:

• Shared accounts with read-only permissions
• Archive or backup accounts
• Accounts in maintenance mode
