When a user disconnects from the hub, we would spawn off a goroutine
which would make a cluster request, and then update the user status
as offline in the DB.
This was another case of unbounded concurrency where the number of
goroutines spawned was user controlled. Therefore, we would see
a clear spike in DB connections on master when a lot of users
would suddenly disconnect.
To fix this, we implement concurrency control in two areas:
1. In making the cluster request. We implement a counting semaphore
per-hub to avoid making unbounded cluster requests.
2. We use a buffered channel with a periodic flusher to process
status updates.
We also add a new store method to upsert multiple statuses
in a single query. The statusUpdateThreshold is set to 32, which means
no more than 32 rows will be upserted at one time, keeping the
SQL query load reasonable.

```release-note
We improve DB connection spikes on user disconnect
by processing status updates in batches.

* enforce License.IsSeatCountEnforced if set
If a license sets `IsSeatCountEnforced`, enforce the user limit therein
as a hard cap.
Fixes: https://mattermost.atlassian.net/browse/CLD-9260
* remove duplicate tests
* Improve user limit error messages and display
- Add separate error messages for licensed vs unlicensed servers
- Licensed servers: "Server exceeds maximum licensed users. ERROR_LICENSED_USERS_LIMITS"
- Unlicensed servers: "Server exceeds safe user limit. ERROR_SAFETY_LIMITS_EXCEEDED"
- Remove redundant "Contact administrator" text from activation errors shown to admins
- Fix system console to display actual server error messages instead of generic "Failed to activate user"

* Add license nil check and test coverage
- Add license != nil check in GetServerLimits to prevent panic
- Add test case to verify graceful handling of license being set to nil
- Ensures fallback to hard-coded limits when license becomes nil

* Fix user limits tests to expect license-specific error IDs
Update test expectations to use the new license-specific error IDs:
- app.user.update_active.license_user_limit.exceeded for licensed server user activation
- api.user.create_user.license_user_limits.exceeded for licensed server user creation
Also update frontend to show actual server error messages instead of generic ones in system console.

* Remove redundant license nil test
The test couldn't meaningfully verify nil license behavior since it relied on
hard-coded constants that can't be modified in the test.

* Add 5% grace period for licensed user limits
- Add calculateGraceLimit() function with 5% or +1 minimum grace
- Apply grace period only to licensed servers with seat count enforcement
- Handle zero user licenses by returning zero grace limit
- Add comprehensive test coverage for grace period scenarios
- Unlicensed servers maintain existing hard-coded limits without grace

* Fix TestCreateUserOrGuestSeatCountEnforcement to account for 5% grace period
The test was failing because it expected user creation to fail at exactly
the license limit, but the implementation now includes a 5% grace period
before enforcement kicks in.
Changes:
- Update test cases to create users up to the grace limit (6 for a 5-user license)
- Add comments explaining the grace period calculation
- Both regular user and guest user creation tests now properly validate
enforcement at the grace limit rather than the base license limit

* Fix TestUpdateActiveWithUserLimits to account for 5% grace period
Update test expectations to match the new grace period behavior:
- At base limit (100) but below grace limit (105): should succeed
- At grace limit (105): should fail
- Above grace limit (106): should fail
This aligns the tests with the license enforcement implementation
that includes a 5% grace period above the licensed user count.
