OpenResty's inline *_by_lua_block parser is the nginx config parser; it
can't reliably handle Lua long brackets ([=[...]=]) embedded in large
rendered snippets. The prometheus role's javascript.js.j2 (logout-icon
DOM-mutation script) collapses to a ~3.4 KB one-liner wrapped in
head_snippets[#... + 1] = [=[<huge_JS>]=], which trips the parser with
"missing the closing long bracket "]=]", the inlined Lua code may be too
long" — the wording is OpenResty's own hint to switch to the file form.
Rendering the body_filter as an external per-app Lua file routes through
Lua's native parser instead, eliminating the limit.
- plugins/lookup/nginx.py: expose <conf_dir>/lua/ as
directories.configuration.lua + add to directories.ensure so
sys-svc-webserver-core auto-creates it
- roles/sys-front-inj-all/templates/body_filter.lua.j2: new — pure Lua
body (formerly inside body_filter_by_lua_block { ... }) plus the
push_snippets Jinja macro
- roles/sys-front-inj-all/templates/location.lua.j2: replace inline
body_filter_by_lua_block with body_filter_by_lua_file pointing at the
per-app .lua
- roles/sys-front-inj-all/tasks/main.yml: render the per-app Lua file
after the feature include_roles (those set the *_code_one_liner vars
the sub.j2 templates depend on); notify restart openresty
