Fix "Illegal invocation" JavaScript error when opening edit modal:
- Remove Bootstrap 2 'hide' class from modal markup
- Add proper Bootstrap 5 modal structure (modal-dialog/modal-content)
- Update JavaScript to use Bootstrap 5 Modal API
- Load dynamic content into .modal-content instead of root modal
- Remove legacy data-toggle attribute from button
The modal now uses the correct Bootstrap 5.3 structure and API,
resolving selector-engine.js errors.

* add 'aria-label' into some elements without the label
* add 'aris-label' into some visual elements
* replace some 'a' elements have a button action to 'button'
no functional change here, but familiar Rails users will see view files in the
locations they expect. this also slightly simplifies controller code
there is one attendant change in the wiki at `rails_3/A1-SQL-Injection-Interpolation.md`
that I'm happy to make after the PR is merged.
