test: Backdrop + MySQL 5.7 SSL connectivity

[AaronFeledy]

Context

Reproduces lando/lando#3833 — user reported TLS/SSL errors when using the Backdrop recipe with MySQL 5.7. The mysql and mysqldump commands from the appserver fail with self-signed certificate errors.

This test duplicates backdrop-mysql-client but targets MySQL 5.7 specifically to confirm whether the SSL issue manifests in the Backdrop recipe context (it didn't reproduce in the bare @lando/php tests).

Note

Low Risk
Only adds a new example and expands CI coverage; no production runtime code paths are modified.

Overview
Adds a new examples/backdrop-mysql57 Leia example that provisions Backdrop and runs connectivity/export checks to catch MySQL 5.7 TLS/SSL client failures when the recipe is configured with database: mysql (no explicit version).

Updates the Backdrop CI workflow to include this new example in the PR test matrix so the scenario is continuously validated.

Missing MySQL 5.7 version pin in database config

High Severity

The database config is set to mysql without a version tag, but this test exists specifically to reproduce MySQL 5.7 SSL issues (lando/lando#3833). Other examples in this repo (e.g. backdrop-custom) use database: mysql:5.7 to pin the version. Without the :5.7 suffix, this will spin up the default MySQL version instead of 5.7, meaning the test won't actually validate the SSL connectivity scenario it was created for.

• ✅ Fixed: Missing MySQL 5.7 version pin in database config
  • Changed database config from mysql to mysql:5.7 to properly test MySQL 5.7 SSL connectivity as intended.
