Module overrides with showtitle, suffix, and header_tag support + CSS

New default.php overrides for 11 Joomla core modules:
- mod_custom (default + updated hero layout)
- mod_articles_latest, mod_articles_popular, mod_articles_news
- mod_articles_category, mod_breadcrumbs, mod_footer
- mod_login (BS5 form with FA7 icons), mod_finder (BS5 search)
- mod_tags_popular (badge layout), mod_tags_similar, mod_related_items

All overrides consistently respect:
- $module->showtitle — renders title only when enabled
- header_tag param — configurable heading level (h1-h6)
- header_class param — custom CSS class on the title
- moduleclass_sfx — custom suffix class on the wrapper

CSS additions in template.css:
- Shared __title styles for all module headings
- List styling for article/tag/related modules
- Newsflash card layout, tag badges, search form, login form
- Breadcrumb and footer module styling
