Bug description

When sharing a folder with custom permissions (e.g., "Read & Share"), the share functions correctly, but the list of shares incorrectly displays the permissions as "View Only," causing confusion for users.

Steps to reproduce

1. Share a folder with another user using custom permissions ("Read & Share").
2. The list of shares for the share owner shows "View only"

The share itself seems to work, only the permissions are shown wrong.

Same goes for the opposite.
If you create a view-only, then open the menu and click "customize", it will be shown as "custom permissions"

This is because we have the default sharing including share to allow users to add link shares to their own account with this UI

	if ($this->shareManager->outgoingServer2ServerSharesAllowed()) {
	$permissions |= Constants::PERMISSION_SHARE;
	}

	hasCustomPermissions() {
	const bundledPermissions = [
	BUNDLED_PERMISSIONS.ALL,
	BUNDLED_PERMISSIONS.READ_ONLY,
	BUNDLED_PERMISSIONS.FILE_DROP,
	]
	return !bundledPermissions.includes(this.share.permissions)
	},
