We implement a cursor based pagination model
to page through the posts in a given thread.
The cursor is a combination of the post.CreateAt+
post.Id to differentiate multiple posts in a given
timestamp.
Some additional parameters like direction, fromPost,
fromCreateAt and perPage were introduced to implement
this.

Summary
A number of performance improvements shipped in v6.5 to support CRT with the ThreadAutoFollow bookkeeping enabled but the frontend features disabled. To prepare for a later enabling of the frontend features by default, we want to encourage customers to re-enable ThreadAutoFollow, and plan to enable this by default in v6.6.

* MM-42282: handle teamId parameter correctly
As per https://community-daily.mattermost.com/core/pl/ugs7ue6e4j8a7cgegk1bxje8to, `ThreadStore.GetThreadsForUser` accepts a `teamId` parameter, but incorrectly handles an empty value of `""` as looking only for channels with an empty `teamId` (aka DMs and GMs) instead of finding all channels and effectively ignoring the team property.
Fixes: https://mattermost.atlassian.net/browse/MM-42282
* break up getThreadsForUser, leverage errgroup
This change breaks up `GetThreadsForUser` in the `ThreadStore` into its constituent `GetTotalUnreadThreads`, `GetTotalThreads`, `GetTotalUnreadMentions`, and the original `GetThreadsForUser` but now solely returning the thread structures. Instead of a monolithic method at the store level, the application layer now handles calling bulk requests, leveraging `errgroup` for simpler parallelization.
This change brings with it a few benefits:
* Simpler code, including more idiomatic usage of squirrel
* Simpler SQL, joining tables only when configured conditions require same. (No performance benefit here, since an unused LEFT JOIN generally has no overhead.)
* Discrete Grafana metrics for each store method, giving us better insight into the performance characteristics in play.
* **Performance boost**: reduced overhead when clearing push notifications.
This last point is what prompted the re-re-reactoring in this PR. As I broke things up, I realized that `clearPushNotificationSync` only used the `TotalUnreadMentions`, but asked for the count of total threads and total unread threads. By exposing the discrete methods, this code path avoids two aggregate queries. We clear notifications when marking a thread as read, and when marking a channel with unread mentions as viewed, so I expect we'll see at least a modest boost to performance from simply not wasting these cycles anymore.
No performance improvements are expected from this PR for the general case of using `GetThreadsForUser` to populate the threads view.
* never discard errors from building queries
* no MustSql

* Further fix
```release-note

After refactoring the channels init, the
config service under channels won't have
the config hash until the product gets
started. This caused an issue during
cluster initialization.
Therefore moved it after the product start.

* deadcode: remove UpdateChannelLastViewedAt
* deadcode: remove ThreadStore.(Save(Multiple)|Update|Delete)
* deadcode: followThead in App.MarkChannelAsUnreadFromPost
* document ThreadMembership, Thread structs
* maintain LastUpdated consistently
Whenever we touch a `ThreadMembership` record, we should be setting `LastUpdated` to the current timestamp. The mobile client relies on this to detect changes to these records.
* simplify: never updateThreads from `App.MarkChannelAsUnreadFromPost`
Change all invocations of `ChannelStore.UpdateLastViewedAtPost` from `App.MarkChannelAsUnreadFromPost` to pass `updateThreads` as `false`. When `ChannelStore.UpdateLastViewedAtPost` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `LastViewed`).
The overall CRT feature continued to work, because `App.MarkChannelAsUnreadFromPost` directly updates the relevant thread memberships via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.UpdateLastViewedAtPost
* simplify: never updateThreads from App.SendNotifications
Change all invocations of `ChannelStore.IncrementMentionCount` from
`App.SendNotifications` to pass `updateThreads` as `false`. When `ChannelStore.IncrementMentionCount` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `UnreadMentions`).
The overall CRT feature continued to work, because `App.SendNotifications` directly updates the relevant thread memberships mention counts via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.IncrementMentionCount
* fix & rename ThreadStore.UpdateUnreadsByChannel
Rename `ThreadStore.UpdateUnreadsByChannel` to `ThreadStore.UpdateLastViewedByThreadIds`, making it unconditionally set the `LastViewed` for the given threads (as well as `LastUpdated`).
All previous invocations of this method that passed `updateViewedTimestamp` have been previously removed.
* unrelated gofmt -w -s changes to satisfy linter
* always set LastUpdated to model.GetMillis()
* deadcode: ThreadStore.SaveMembership
* fix TestMarkUnreadWithThreads
* MM-40302: CRT, use updateThreads param vs. MarkAllAsReadInChannels
`MarkAllAsReadInChannels` was the subject of a significant performance regression in v5.37 and is known to be very inefficient, by virtue of always writing to an ever increasing number of rows, and doing so on common events like simply viewing a channel.
Fortunately, `ChannelStore.UpdateLastViewedAt` already supported an `updateThreads` parameter that implemented the start of an improved algorithm: query the set of threads with newer posts, and then update only /those/. Missing was the need to reset the `UnreadMentions`, but thanks to the previous simplifications in #19523, we can make this change largely without impacting other semantics.

This is more of a general refactor of the initialization
process which should allow us to pass services more
easily.
The changes are minimal to keep the scope limited.
For now, the objective is to pass the file service
to the Channels product. For that, it was required
to move some of the enterprise interfaces under Channels
from Server.
We also create a filestore field in the server to
avoid creating filestore reference every time
we make a filestore operation. This will be later
passed on to the Channels product.
Also removed an unnecessary test.
The test was working so far because we were creating
the filebackend every time for every request. But
we should go via UpdateConfig call which would fail,
were we to assign an invalid filestore name.
So we were actually testing for a different thing.
Therefore, removed the test.
```release-note
NONE
```
Previously, we were incrementing mentions one-by-one
all concurrently in an unbounded fashion.
This would cause a big spike in memory usage if there
were an `@all` mention in a large channel.
We fix this by changing the SQL query to take all userIDs
at once.
