test: add MySQL client compatibility test (PHP 8.4 + MySQL 8.0)

[AaronFeledy]

Adds an integration test for the MySQL client auto-detection with the backdrop recipe, covering the issues reported in lando/lando#3833.

Tests:

• MySQL client installed (not MariaDB) via auto-detection
• No SSL/TLS certificate errors on connect
• bee db-export works without SSL errors
• Exported SQL uses MySQL dump format (not MariaDB dump)

Expected to fail until @lando/php ships the recipe-prefixed db_client detection fix (lando/php#223).

Note

Medium Risk
Adds a new integration test matrix entry and updates @lando/php, which can change runtime PHP/service behavior in CI and for consumers relying on the plugin’s bundled dependencies.

Overview
Adds a new MySQL-client compatibility integration test by introducing examples/backdrop-mysql-client (PHP 8.4 + MySQL 8.0) and wiring it into the GitHub Actions Leia matrix to validate client auto-detection, SSL-free connectivity, and MySQL-format exports.

Updates dependencies by bumping @lando/php to ^1.11.0 (with corresponding lockfile update) and recording the change in CHANGELOG.md.

[cursor]

Bugbot Autofix prepared fixes for 2 of the 2 bugs found in the latest run.

• ✅ Fixed: Inverted grep on multi-line file always passes
  • Replaced grep -qiv with the correct negation pattern (grep -qi || echo $? | grep 1) that properly verifies MariaDB dump format is not present.
• ✅ Fixed: Dump footer line defeats MariaDB negation check
  • Replaced grep -qiv with the correct negation pattern (grep -qi || echo $? | grep 1) that properly checks for MariaDB in Dump lines.
