Better hide reset password functionality for LDAP users

[snipe]

We were already disallowing LDAP users to save new passwords, but there were a few places where we didn't hide the buttons. (It would redirect with error on save, and didn't actually save the password, but it was a clunkier user experience.

This now does a better job of hiding those elements if the user has ldap_import set to 1 on their account.

TODO: We should probably come up with a better way of explaining what ldap_import actually does in the modern world. Really, it just determines whether or not the user can edit their password, and we could probably do a better job of explaining that instead of the old "LDAP Enabled" text. In fact, perhaps change the actual fieldname to reflect what this actually does.

PR Summary

• Improved Password Reset Process
  The process of resetting passwords has been updated to account for users who have their details imported using LDAP. Users that fall into this category will now be appropriately handled by the system.

• Updates to Profile Controller
  The ProfileController's password method has undergone modification. Now, it redirects LDAP imported users accompanied by an error message if they attempt a password change, reinforcing our new password policy.

• Bulk Password Reset Functionality Enhancement
  The bulk password reset feature in the BulkUsersController also got an upgrade to exclude LDAP users from its purview. This is to ensure these users don't undergo unexpected password resets.

• Language Entries Addition in general.php
  There are new language entries in general.php that are related to user-managed passwords. This addition was made to address localisation and better communication with the users.

• Conditional Rendering in Account View
  The "Change Password" button will now be conditionally displayed in the account view files depending on the user status — it won't show up for LDAP users. This includes better user interface handling and subsequent advantages in overall user experience.

• Updated References in bulk-edit.blade.php
  Changes were implemented in the bulk-edit.blade.php file that involved updating the references to use the new language keys for LDAP related settings. These linguistic updates bring about better accuracy and improved comprehension for users regarding LDAP settings.
