fix(e2e): load text domain at init priority 1 and disable WP_DEBUG_DISPLAY

In WP 6.7+, register_block_type() translates block.json strings via __()
at init priority 10, before load_plugin_textdomain() ran (also priority
10, but registered later). This triggered the JIT textdomain notice which
output text before headers, breaking cookie-based login in E2E tests.

Moving load_plugin_textdomain to priority 1 ensures the domain is loaded
before any __() calls during block registration.

WP_DEBUG_DISPLAY: false prevents any future PHP notices from reaching the
browser output stream, keeping wp-login.php headers intact in wp-env.
