form_controller.connect() now blurs the previously focused element and
explicitly focuses the [autofocus] element when a form is inserted into
the DOM (via Turbo Stream). Only runs when an [autofocus] element is
present, so closing forms and other stream updates are unaffected.
Remove all onclick='this.blur()' inline handlers from templates — they
were a workaround for the same autofocus problem, now solved properly
via the Stimulus lifecycle.

Add stimulus-rails gem and wire up 7 controllers:
- measurements_view_controller: view toggle (compact/wide) via localStorage
- measurements_controller: grouped rows MutationObserver
- charts_controller: Plotly chart rendering
- form_controller: keyboard shortcuts (Escape/Enter) and submit validation
- details_controller: quantity picker state, focusout close, MutationObserver
- readout_unit_controller: default unit button enable/disable + PATCH submission
- drag_controller: drag-and-drop for quantity reparenting and unit rebasing
Remove all inline onclick/onkeydown/ondrag*/onsubmit handlers from templates.
Remove all window.* global exports from application.js.
Remove bare <script> block from measurements/_form.html.erb.
Remove turbo:load listeners for behavior now in controller connect().
application.js now only contains: Turbo Stream custom action definitions
and the showPage visibility listener.
Document Stimulus conventions in CLAUDE.md.

* adding streams in client breaks things (e.g. autofocus)
* some tasks need to be performed in one stream action to avoid
flickering (e.g. table row substitution)
