Align CI workflow PHP version with Dockerfile

[Copilot]

The CI workflow tested with PHP 8.4 while the Dockerfile used PHP 8.2, creating environment inconsistency.

Changes

• Updated .github/workflows/app-ci.yaml to use PHP 8.2 in the test matrix

Both environments now use the minimum supported version (composer.json requires ^8.2), ensuring compatibility issues are caught consistently across local development and CI.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• pecl.php.net
  • Triggering command: /usr/local/bin/php /usr/local/bin/php -C -q -d include_path=/usr/local/lib/php -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv=On /usr/local/lib/php/peclcmd.php install xdebug ndor/bin/bash /bin/bash (dns block)
  • Triggering command: /usr/local/bin/php /usr/local/bin/php -C -q -d include_path=/usr/local/lib/php -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv=On /usr/local/lib/php/peclcmd.php search xdebug .d/chrony-onofflrm -f ext/opcache/jit/ir/ir_fold_hash.h /usr/bin/sed (dns block)
  • Triggering command: /usr/local/bin/php /usr/local/bin/php -C -q -d include_path=/usr/local/lib/php -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv=On /usr/local/lib/php/peclcmd.php install xdebug _FILE_OFFSET_BIT \ strip --strip-all "$@" || : u/14/cc1 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
