Fix: Collabora proxy should load iframe with WOPISrc in query string, not form submission

Browse Source 
- Changed from form POST submission to direct iframe load
- WOPISrc goes in Collabora URL query string, not as form parameter
- This matches Collabora's expected request format for WOPI integration
