Extract HTTPLUA and HTTPREXX into separate projects

 - **UFSD-only docroot** — Remove DD-based file serving (`/DD:HTML(...)` paths), static files only from UFS
 - **Remove embedded FTPD** — FTP functionality available separately
 - **Remove MQTT telemetry** — HTTPT struct, telemetry_thread, mqtt370 dependency
-- **CGIs disabled by default** — No CGIs are registered unless explicitly configured in Parmlib. All existing CGI modules remain in the codebase but are only active when configured.
+- **Extract HTTPLUA/HTTPREXX** — Lua and REXX CGI handlers moved to separate projects (mvslovers/httplua, mvslovers/httprexx), lua370 dependency removed
+- **CGIs disabled by default** — No CGIs are registered unless explicitly configured in Parmlib.

 2. **TSK-110 Fehlende Status-Codes** (XS, High) — Missing HTTP status codes
 3. **TSK-108 HTTP Parsing härten** (L, High) — Harden HTTP request parsing
-4. **TSK-104 HTTPLUA auslagern** (L, Medium) — Extract HTTPLUA into separate module
