Split make_server_env, eliminate all runtime sx_ref imports, fix auth-menu tests

make_server_env split into 7 focused setup functions:
- setup_browser_stubs (22 DOM no-ops)
- setup_scope_env (18 scope primitives from sx_scope.ml)
- setup_evaluator_bridge (CEK eval-expr, trampoline, expand-macro, etc.)
- setup_introspection (type predicates, component/lambda accessors)
- setup_type_operations (string/env/dict/equality/parser helpers)
- setup_html_tags (~100 HTML tag functions)
- setup_io_env (query, action, helper IO bridge)

Eliminate ALL runtime sx_ref.py imports:
- sx/sxc/pages/helpers.py: 24 imports → _ocaml_helpers.py bridge
- sx/sxc/pages/sx_router.py: remove SX_USE_REF fallback
- shared/sx/query_registry.py: use register_components instead of eval

Unify JIT compilation: pre-compile list derived from allowlist
(no manual duplication), only compiler internals pre-compiled.

Fix test_components auth-menu: ~auth-menu → ~shared:fragments/auth-menu

Tests: 1114 OCaml, 29/29 components, 35/35 regression, 6/6 Playwright
