refactor: Integration entity out of db watcher

[ricardogarim]

As per the updates mentioned in PROJ-7 SCA-4 and ADR #74, this pull request focuses on relocating Integration entity out of DB Watcher service.

Quick context to public readers

In essence, this modification empowers RocketChat's app to directly call listeners through the api.broadcast global function, eliminating the reliance on MongoDB Change Stream data propagation

Why is this beneficial? It provides better control over notifying users by enabling more precise use-case management. Unlike Change Streams, which notify every action on Mongo's documents and sometimes might result in unnecessary duplicate notifications. Moreover, it contributes to the future removal of the DB Watcher deployment, thereby optimizing resource utilization.

Proposed changes

Key changes include:

• Conditionally incorporating Permissions entity import within DB watchers on application startup based on the dbWatchersDisabled flag.
• Enabling support for the following use cases to directly trigger watch.integrations listener event, subject to the dbWatchersDisabled flag.

Updated use cases.

Use Case	Route/Trigger	Notes
deleteUser	Route POST users.delete
updateRoomName	Function existing within saveRoomName on channel-settings package
deleteOutgoingIntegration deleteIncomingIntegration	Route POST integrations.remove
updateOutgoingIntegration updateIncomingIntegration	Route PUT integrations.update
addIncomingIntegration	Route POST integrations.create
executeTriggerUrl	Function executeTriggerUrl on RocketChatIntegrationHandler file

Steps to test or reproduce

1. Start RocketChat's application with the DISABLE_DB_WATCHERS flag set to true.
2. Perform a POST request to above given endpoints available on updated use cases.

Further comments

To maintain consistency and avoid potential regressions, event names and signatures have been kept unchanged on both the client and app sides. This decision streamlines efforts and mitigates the risk of unintended consequences.
