Fix translation loading timing by moving from plugins_loaded to init hook

[Copilot]

Problem

The translation loading for the wp-user-manager domain was triggered too early, occurring on the plugins_loaded hook with priority 0. This is against WordPress best practices and can cause translation loading warnings in debug logs.

Solution

Moved the textdomain loading from the plugins_loaded hook to the init hook, which is the recommended timing for translation loading in WordPress.

Before:

add_action( 'plugins_loaded', array( $this, 'load_textdomain' ), 0 );

After:

add_action( 'init', array( $this, 'load_textdomain' ) );

Changes Made

• Modified includes/class-wp-user-manager.php line 449 to use the init hook instead of plugins_loaded
• Removed the priority parameter as it's not needed on the init hook
• Maintains proper execution order with the main plugin initialization

Verification

• ✅ Follows WordPress translation loading best practices
• ✅ No conflicts with existing translation usage in the codebase
• ✅ Proper hook execution order maintained (plugins_loaded → init)
• ✅ Syntax validation passed
• ✅ Only location where load_plugin_textdomain is called

This change ensures translations are loaded at the appropriate time and eliminates the early loading warnings.

Fixes #405.

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 my firewall allow list
