* MM-68016, MM-68017, MM-68018 Add plugin pre-hooks for channel member add, team member add, and channel archive
Enable plugins to intercept and reject (or modify) three operations before
they are persisted: adding a channel member, adding a team member, and
archiving a channel. These are the three high-priority hooks from epic
MM-68003.

* fix: update file rejection handling to use 403 Forbidden status and include rejection reason header
* Fix nil pointer panic in runFileWillBeDownloadedHook
The atomic.Value in runFileWillBeDownloadedHook can be nil if no
plugins implement the FileWillBeDownloaded hook. This causes a panic
when trying to assert the nil interface to string.
This fix adds a nil check before the type assertion, defaulting to
an empty string (which allows the download) when no hooks have run.
Fixes:
- TestUploadDataMultipart/success panic
- TestUploadDataMultipart/resume_success panic
* test: move the logout test last
* chore: restored accidential deletion

* revert: conflict merge
* fix: add missing isFileRejected prop to SingleImageView tests
* fix: mock fetch in SingleImageView tests for async thumbnail check
The component now performs an async fetch to check thumbnail availability
before rendering. Tests need to mock fetch and use waitFor to handle
the async state updates.
* refactor: move hook logic to app layer
* chore: update version to 11.5
* Scope file download rejection toast to the requesting connection
Thread the Connection-Id header through RunFileWillBeDownloadedHook and
sendFileDownloadRejectedEvent so the WebSocket event is sent only to the
connection that initiated the download, instead of all connections for
the user.

* Upgrade Go to 1.24.3
Updates the following files:
- server/.go-version: 1.23.9 → 1.24.3
- server/build/Dockerfile.buildenv: golang:1.23.9-bullseye → golang:1.24.3-bullseye
- server/go.mod: go 1.23.0 → go 1.24.3, toolchain go1.23.9 → go1.24.3
- server/public/go.mod: go 1.23.0 → go 1.24.3, toolchain go1.23.9 → go1.24.3
Also fixes non-constant format string errors introduced by Go 1.24.3's stricter format string checking:
- Added response() helper function in slashcommands/util.go for simple string responses
- Removed unused responsef() function from slashcommands/util.go
- Replaced responsef() with response() for translated strings that don't need formatting
- Fixed fmt.Errorf and fmt.Fprintf calls to use proper format verbs instead of string concatenation
- Updated marketplace buildURL to handle format strings conditionally

Remove changes related to the unshipped threads everywhere feature, including commits b8da473da7 and 9f9e19e05d.
Since a version of Playbooks shipped calling this experimental API, keep a `nil` implementation to avoid breaking compatibility. We remove the hooks altogether, but keep the numbering again to avoid breaking compatbility.
Fixes: https://mattermost.atlassian.net/browse/MM-53358
It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
https://mattermost.atlassian.net/browse/MM-53032
```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public
```
