This commit introduces a unified mechanism to configure client_max_body_size
for both HTML and upload locations in the sys-svc-proxy role. The directive
is now injected early in html.conf.j2 and moved to a dedicated block in
upload.conf.j2 to ensure consistent behavior for large file uploads such as
OpenProject attachments.
Additionally:
- Added client_max_body_size variable override from web-app-openproject (set to 30m).
- Reordered header includes to avoid duplicate injection.
- Improved comments and structure for better clarity.
