- Add GET /printers/{printer_id} route to pages.py with LEFT OUTER JOINs on Client and Driver
- Create printer_detail.html full-page template showing all config fields and driver info
- Display "No driver assigned" when driver FK is null
- Add disabled "Regenerate Package" button (Phase 4 placeholder)
- Make printer names in printer_list.html clickable links to detail page
- imptune/api/printers.py: POST /printers (all form fields, checkbox->bool,
FK resolution), DELETE /printers/{id}, grouped list renderer with LEFT JOIN
- imptune/api/clients.py: POST /clients with duplicate-name handling
- imptune/api/pages.py: GET /printers and GET /clients page routes
- imptune/main.py: register printers + clients routers; close db on shutdown
- imptune/db/database.py: close existing connection before re-init (test isolation)
- templates: printers.html, clients.html, printer_form.html (Alpine.js port
auto-derivation), printer_list.html (grouped by client), client_list.html
- tests/conftest.py: close test-thread db connection in fixture teardown
- tests/test_printer_crud.py: updated to use list(select().where()) for DB
queries (avoids Peewee thread-local cursor caching across test boundaries)
Auto-fix [Rule 1 - Bug]: DB test isolation — Peewee thread-local connections
persisted across tests causing stale DB reads; fixed via conftest teardown and
lifespan db.close() on shutdown.
