* MM-34080: Removing sqlite entirely
The initial commit missed removing this blank import.
So the library still remained in our vendor directory.
Removing it for good now.
Bye bye sqlite.
https://mattermost.atlassian.net/browse/MM-34080
* fix go.mod
This is a deadlock due to reversed locking order of the SidebarChannels
and SidebarCategories table.
I could not find the exact culprit query from the deadlock output
because it only shows the last query a transaction is running. And from looking
at the code, the only query that runs "UPDATE SidebarCategories SET DisplayName = ?, Sorting = ? WHERE Id = ?"
is UpdateSidebarCategories. But for the deadlock to happen, it has to lock
SidebarChannels _first_, and then _then_ lock SidebarCategories.
Looking a bit more throughly, I found that DeleteSidebarCategory does indeed
lock the tables in an inverse way and if DeleteSidebarCategory runs concurrently with
UpdateSidebarCategories, they will deadlock.
Here's how it will happen.
```
tx1
DELETE FROM SidebarChannels WHERE CategoryId = 'xx';
tx2
UPDATE SidebarCategories SET DisplayName='dn' WHERE Id='xx';
tx2
DELETE FROM SidebarChannels WHERE (ChannelId IN ('yy') AND CategoryId = 'xx');
tx1
DELETE FROM SidebarCategories WHERE Id = 'xx';
```
And then we see:
ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction
To fix this, we simply reorder the Delete query to lock the SidebarCategories first,
and then SidebarChannels.
In fact, any transaction updating/deleting rows from those two tables should always operate on that order
if possible.

```release-note
Fixed a database deadlock that can happen if a sidebar category is updated and deleted at the same time.

* MM-33789: Revert fallback to master for GetAllProfilesInChannel
This fixes a regression introduced in https://github.com/mattermost/mattermost-server/pull/16911.
It was causing problems with too many invalidations and overloading the writer instance for big installations.
Reverting this does not affect correctness at all because it was done out of abundance of caution and the
idea at that point was it was to be done for all caches.

* MM-30882: Fix read-after-write issue for demoting user
In (*App).DemoteUserToGuest, we would demote a user, and then immediately
read it back to do future operations from the user. This reading back
of the user had the effect of sticking the old value into the cache
after which it would never be updated.
There was another issue along with this, which was when the invalidation
message would broadcast across the cluster, it would hit the cache invalidation
problem where an unrelated store call would miss the cache because
it was invalidated, and then again read from replica and stick the old value.
To fix all these, we return the new value directly from the store method
to avoid having the app to read it again.
And we add a map in the localcache layer which tracks invalidations made,
and then switch to use master if it's true.
The core change is fairly limited, but due to changing the store method signatures,
a lot of code needed to be updated to pass "context.Background". Therefore the PR
just "appears" to be big, but the main changes are limited to app/user.go,
sqlstore/user_store.go and user_layer.go
