* [MM-66789] Fix arbitrary file read vulnerability in advanced logging
Add path validation to prevent reading files outside the logging root
directory via GetAdvancedLogs (used in support packet generation).
Security controls:
- Validate file paths are within logging root before reading
- Support MM_LOG_PATH environment variable to allow system admins
to configure a custom logging root directory
- Resolve symlinks to prevent bypass attacks
- Detect and block path traversal attempts
Also adds:
- Audit logging for support packet generation
- Config-time validation that logs errors for paths outside logging
root (will become blocking in future version)
- Comprehensive test coverage for path validation
* Update server/channels/app/platform/log_test.go

* fix linter errors
* Update server/channels/api4/system.go
Co-authored-by: Ben Schumacher <ben.schumacher@mattermost.com>
* Simplify unit tests for platform/log_test.go by moving some test logic to config/logger_test.go
* Fix unit tests requiring logging root to be set
* enforce LogSettings.FileLocation path validation; simplify path checking
* fix linter errors
* use dir in logging root for all unit test logging
* MM_LOG_PATH is set once, centrally, for all tests
* fix flaky test
* fix flaky test
