fix(roles): follow the php scripts to their new folder

The relocation in dfe7a7fdd moved provision_mcp.php,
provision_mcp_identity.php and the ai_engine pair into files/php/ but left
their callers pointing at the old locations, so moodle's and snipe-it's MCP
provisioning and wordpress's AI Engine configuration resolved a path that
no longer exists.

The reference sweep that accompanied the move searched for python, shell,
ruby and sql folders and never looked for php, so these four lookups were
missed.
