Expose per-suite disabled WOPI extensions

[amamus]

oCIS-Alignment-Issue: 26

Problem

The current collaboration service supports disabling selected WOPI file extensions per Office suite, but the chart's closed Office-suite values model does not expose that setting.

References

• Current collaboration WOPI configuration
• Target Office-suite values
• Target collaboration workload template

Desired change

Add a disabledExtensions list to each configured Office suite and render it for that suite as the comma-separated COLLABORATION_WOPI_DISABLED_EXTENSIONS value.

Update the values schema and generated values documentation as part of the change.

Acceptance criteria

• Every Office-suite entry accepts a list of disabled extensions.
• The corresponding collaboration Deployment receives one comma-separated value in source order.
• An empty or omitted list preserves current behavior and does not leak configuration between suites.
• Schema validation rejects invalid element types and malformed extension values.
• Multi-suite rendering tests verify that each collaboration Deployment receives only its own list.

Impact

Operators currently cannot disable selected file formats in individual Office integrations.
