feat(core): Update plugin title rendering with default icon

Replaces inline plugin title HTML with a reusable template in
`template_code.py`. Adds a default icon for plugins without custom icons
and updates the table logic to use this template.
Removes redundant logic from the `render_title_long` method to improve
maintainability.
Changes the `order_by` field in `plugins.py` from `name` to
`title_long`.

Fixes #20264
