Bump to PHP 8.3 minimum, migrate to Mago QA toolchain, add Pdo\Result coverage

php-db/phpdb 0.6.x added getQueryResult() to Driver\ResultInterface, which
Sqlite already satisfies for free via the shared core Pdo\Result class (no
sqlite-owned Result class exists). Ports the core's exhaustive Pdo\Result
unit test suite to cover it, matching the coverage mysql/pgsql carry for
their own Result classes.

Also replaces laminas-coding-standard/phpstan with the shared
php-db/phpdb-qa-tools Mago toolchain, mirroring phpdb-qa-analysis-sql:
mago.toml extending the shared base, the qa-tools phpunit.xml.dist
template, mago-based composer scripts, and the reusable CI workflow.
Pre-existing lint/analyzer findings in untouched code are captured in
lint-baseline.toml/analyzer-baseline.toml rather than fixed here.
