Bootstrap/Load: Send HTTP headers after querying posts in `WP::main()`.

By running `WP::send_headers()` after posts have been queried, we can ensure that conditional tags like `is_front_page()`, `is_home()`, etc. work as expected.

This provides better context and more flexibility when adjusting HTTP headers via the `wp_headers` filter or `send_headers` action.

Previously, the earliest action where conditional tags worked correctly was `wp`.

Includes moving the `X-Pingback` header, previously sent in `WP::handle_404()`​ after posts have been queried, to a more appropriate place in `WP::send_headers()`.

Follow-up to [2627], [34442].
