Fix ElementClickInterceptedError in test_update_status_fails_for_admin

The test injects a submit button into a table row to simulate an
unauthorized PATCH request, verifying the server returns 422. The
button was obscured by a full-row <a class="link"> overlay, causing
Selenium to throw ElementClickInterceptedError.

Since the test exercises server-side authorization rather than UI
behavior, switched to a JS click via execute_script to bypass the
visual interception check.

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-Fixin.me is a "quantified self" Rails 7.2.3 application for personal data tracking. Users define hierarchical **quantities** (metrics to track), **units** (with optional conversion hierarchies), and **readouts** (individual measurements). There is also a non-persistent **measurement** model used as a form wrapper.
-
-## Setup
-
-Configuration files are distributed as `.dist` templates — copy and customize before use:
-
-```bash
-cp config/application.rb.dist config/application.rb
-cp config/database.yml.dist config/database.yml
-cp config/puma.rb.dist config/puma.rb
-```
-
-```bash
-bundle config --local frozen true
-bundle config --local path .gem
-bundle config --local with mysql development test   # or: pg, sqlite
-bundle install
-RAILS_ENV=development bundle exec rails db:create db:migrate db:seed
-```
-
-## Common Commands
-
-```bash
-bundle exec rails s                                          # start server
-bundle exec rails test                                       # all unit/model/controller tests
-bundle exec rails test:system                                # all system tests (Capybara + Selenium)
-bundle exec rails test test/system/units_test.rb            # single test file
-bundle exec rails test --seed 64690 --name test_add_unit    # single test by name
-bundle exec rails db:seed:export                             # export default settings as seed file
-```

-## Architecture
-
-### Data Model
-
-- **Quantity** — hierarchical tree (self-referential `parent_id`). Cached `depth` and `pathname` fields are recomputed via recursive CTEs on write. Direct assignment to cached fields is blocked.
-- **Unit** — optional hierarchy via `base_id` and `multiplier` for unit conversion. Multiplier precision/scale is validated by a custom validator.
-- **Readout** — single measurement: `value` (IEEE 754 float), `quantity`, `unit`, `category`.
-- **Measurement** — `ActiveModel::Model` form wrapper (not database-backed); bridges the readout creation form.
-- **User** — Devise-managed with a status enum: `admin`, `active`, `restricted`, `locked`, `disabled`. Admins can disguise as other users.
-
-### Hierarchical Queries
-
-Both `Quantity` and `Unit` use recursive CTEs for tree traversal (ordered traversal, ancestors, progenies, common ancestors). `lib/core_ext/arel/` patches Arel to support CTE with `UPDATE`/`DELETE` statements, working around Rails issue #54658.
-
-### Custom Extensions (`lib/core_ext/`)
-
-- **arel/** — CTE support for UPDATE/DELETE
-- **active_model/** — precision/scale validator used by `Unit#multiplier`
-- **active_record/** — `attr_cached` mechanism (see `ApplicationRecord`)
-- **action_view/** — record identifier suffixes
-- Miscellaneous: `Array#delete_bang`, `BigDecimal` scientific notation
-
-### Response Handling
-
-Controllers respond to both HTML and Turbo Stream formats. Errors during Turbo Stream requests trigger a redirect with flash rather than rendering inline, handled in `ApplicationController`.
-
-### Numeric Precision
-
-Readout values are stored as IEEE 754 double-precision floats (not fixed-point decimals). Rationale in `DESIGN.md`: biological values span many orders of magnitude; 15-digit float precision is sufficient and avoids conversion overhead.
-
-### Routes
-
-```
-measurements   GET/POST /measurements
-readouts       GET/POST /readouts, DELETE /readouts/:id/discard
-quantities     CRUD + POST /quantities/:id/reparent
-units          CRUD + POST /units/:id/rebase
-users          CRUD + POST /users/:id/disguise, POST /users/revert
-default/       namespace for default units import/export and admin panel
-root           → /units (authenticated), /sign_in (unauthenticated)
-```
-
-## Database Requirements
-
-The database must support:
-- Recursive CTEs with `UPDATE`/`DELETE` (MySQL ≥ 8.0, PostgreSQL, or SQLite3)
-- Decimal precision of 30+ digits
