Fixed tooltip not loading on encrypted field lock icon on asset detail view

[snipe]

This fixes an issue reported in SC-23552 where the "encrypted field" tooltip was showing as blank - and also fixes one we didn't notice, which is that the tooltip doesn't load at all if you switch models on edit or create, since the DOM is already loaded when we ajax in those form fields.

PR Summary

• Integration of Bootstrap 3 Tooltip
  Bootstrap 3's tooltip feature has been added in resources/views/layouts/default.blade.php, which will allow additional informational text to be shown when users hover over certain elements in the web application.

• Tooltip Re-initialization After DOM Load
  A new script has been implemented in resources/views/models/custom_fields_form.blade.php. This allows the tooltip feature to be re-initialized and function as expected after the Document Object Model (DOM) has fully loaded on the page. This ensures the tooltip feature continues working even if the page content changes dynamically.
