* docs: Add v11.4 log path restriction documentation

Document the new MM_LOG_PATH environment variable and log path
validation feature introduced in Mattermost v11.4.0. This security
enhancement restricts log file locations to a designated root
directory to prevent unauthorized filesystem access via logging
configuration.

Changes include:

Environment Variables:
- Add MM_LOG_PATH documentation with purpose, default, usage examples
- Document validation behavior and error handling

Logging Configuration:
- Add comprehensive "Log path restrictions" section
- Document path validation mechanism (absolute path resolution,
  symlink handling, directory boundary enforcement)
- Provide valid and invalid configuration examples
- Add troubleshooting guidance for log access errors
- Update file target configuration to note v11.4 path requirements

Support Packet Generation:
- Document audit logging for support packet generation (v11.4+)
- Note audit trail metadata for compliance tracking

Configuration Settings Reference:
- Update FileLocation setting with v11.4 validation note
- Update AdvancedLoggingJSON with path restriction requirements
- Add cross-references to detailed logging documentation

Security Guide:
- Add log path restrictions to security features list
- Highlight access control and configuration integrity benefits

Troubleshooting:
- Add "Log files not accessible" troubleshooting section
- Provide step-by-step resolution procedures
- Include decision flowchart for diagnosing log access issues
- Offer migration paths for existing custom log configurations

Addresses both System Admin and Risk Assessor personas with
practical configuration guidance, security context, and
comprehensive troubleshooting support.

Resolves #8730

* docs: Clarify log path validation behavior per technical feedback

Update documentation to accurately reflect that log paths outside the
root directory generate error logs and are excluded from support packet
downloads, rather than being blocked from writing. Softened "must be"
language to "should be" to align with actual enforcement level.

… is not a leader node (#8707)

* docs: Document v11.4 cluster job execution debug messages

Add documentation for new debug log messages introduced in Mattermost
v11.4.0 that help system admins understand cluster job execution
behavior in high availability deployments.

Changes:
- Added new section in logging.rst documenting cluster job debug
  messages for scheduled posts, DND status reset, and post reminders
- Added notes in high-availability-cluster-based-deployment.rst about
  debug messages in leader election and job server sections
- Added tip in experimental-configuration-settings.rst about verifying
  cluster job execution with debug messages

These DEBUG-level messages indicate normal operation when non-leader
nodes skip job execution, helping admins troubleshoot cluster behavior.

Resolves #8706

* docs: Clarify debug log messages apply only to Recurring Tasks

Update documentation to specify that v11.4 debug log messages for
cluster job execution apply only to Recurring Tasks (Scheduled Posts,
Post Reminders, and DND Status Reset), not all cluster jobs.

This prevents admins from incorrectly assuming the absence of these
debug messages for other job types (Elasticsearch indexing, SAML sync,
LDAP sync, etc.) indicates a problem with job execution.
