Allow external users to view recently opened/viewed links

Description

Add the ability for external users to view shared links history from external share account.

Current build

If an external share is accessed using a link and not shared with specific external user, external user may only view this page again if the user subscribes to the share; otherwise user must find the link in order to access the share.

Future build

There is an option for external user to view history of viewed links, for example as,

History
Recently viewed

Database design

Table: external_user_activity
We could use it to save information about all action types:
Added attachments, added comments, subscribe/unsubscribe actions

column name	column type	opts
id	bigserial	autincrement
external_user_id	int	required
activity_type	External_User_Activity_Type	required
share_id	bigint	required
create_date	timestamp_with_timezone	required
title	string	Confluence page name
page_id	int	required

External_User_Activity_Type:
Page View, Attachement Add, Comment Add, Comment Remove, Comment Update. Subscribe, Unsubscribe.

// Example enum type        <sql>            CREATE TYPE document_email_status AS ENUM ('SEND', 'DELIVERED', 'ERROR');            --rollback DROP TYPE document_email_status;        </sql>

        service.increaseOpen(share);        externalUserService.collectActivity(ExternalUserActivityType.PAGE_VIEW,            shareId,            content.id(),            spc.user().id()            )

AFTER: Make activity not clickable if share was deleted.
