Bulk Scrape Enablement with Confirmation Modal

What Was Built

Bulk scrape enablement flow: users can select multiple scrape candidate sources via checkboxes, see a sticky action bar with selected count, open a confirmation modal, and bulk-enable scraping for all selected sources in one action.

Commits

• 391e957 feat: add BulkScrapeEnablementsController with route and tests
• b0d1995 feat(views): add bulk scrape checkboxes, action bar, and confirmation modal
• ef4a71d feat(js): extend select-all controller with action bar and count targets

Tasks Completed

1. BulkScrapeEnablementsController - Created controller with create action that bulk-updates scraping_enabled and scraper_adapter on selected sources. Responds with Turbo Stream (toast + redirect) and HTML formats. Handles empty selection with warning.
2. Route - Added resources :bulk_scrape_enablements, only: :create as top-level route in engine.
3. Checkboxes and bulk action bar - Wrapped sources table in form with select-all Stimulus controller. Added header checkbox (master toggle) and row checkboxes for scrape candidate sources only. Added sticky bottom action bar showing selected count and "Enable Scraping" button.
4. Confirmation modal - Created _bulk_scrape_enable_modal.html.erb partial using existing modal Stimulus controller. Shows warning text and "Confirm Enable" submit button wired into the bulk form.
5. Select-all controller extension - Added actionBar and count targets. New updateActionBar() method shows/hides action bar and updates count on every checkbox toggle.

Deviations

• Plan referenced SourceMonitor.config.scrapers.default_adapter_name which does not exist. Used hardcoded "readability" string instead (matches Sources::Params.default_attributes convention).
• Updated _empty_state_row.html.erb colspan from 7 to 10 to account for the new checkbox column and correct the pre-existing count.
• Route test uses functional verification (POST + assert redirect) instead of assert_routing since the engine is mounted at a prefix that complicates path matching.
