/**
 * DATABASE CONFIGURATION (multi-tenant)
 *
 * This app now serves MANY companies from ONE codebase. Each company has
 * its own separate database (created via the Super Admin panel). Which
 * database we connect to is decided per-request from the logged-in
 * user's session (set at login.php after routing through the master DB).
 *
 * Nothing else in the app needs to change - every module still just
 * uses the global $pdo, it now simply points at the correct company's
 * database automatically.
