Complete window.py cleanup - remove 400 lines of obsolete code

Removed obsolete UI methods now handled by RequestTabWidget:
- _setup_method_dropdown, _setup_request_tabs, _setup_response_tabs
- _build_request_from_ui, _load_request_to_ui
- _display_response, _display_error
- _extract_content_type, _get_language_from_content_type, _format_response_body
- on_add_header_clicked, _add_header_row, _on_header_remove
- _setup_sourceview_theme, _setup_request_body_theme
- _update_tab_indicator (now handled internally by widgets)

Added new HTTP handling:
- _on_send_clicked now works with RequestTabWidget
- Properly handles request/response through widget interface
- Updates history after requests complete

Result: 1237 lines → 841 lines (-396 lines, -32%)
App builds and runs successfully!
