ci: migrate integration tests from SVN to wp-env

Modernises the integration test infrastructure to use wp-env instead of
the legacy SVN-based test setup. GitHub-hosted runners no longer include
SVN by default, causing test failures. This migration aligns with
WordPress's recommended testing approach and ensures consistency between
local development and CI environments.

Updates the workflow to install wp-env, removes MySQL service
configuration (now provided by wp-env), and eliminates the prepare-ci
script. The WordPress matrix now uses concrete version numbers ('6.8')
and 'master' instead of 'latest' and 'trunk', as wp-env expects actual
Git branch/tag references.

Renames composer scripts to reflect their integration test purpose:
test → test-integration, test-ms → test-integration-ms.

Updates clover.xml output path to .phpunit.cache/coverage/ and adds
a workflow step to copy the coverage report from the wp-env container
for Codecov upload.

Removes bin/install-wp-tests.sh (182 lines) which is no longer needed.
