Fix WordPress scaffolding gap; add delete project + WP admin link

Found via real usage: creating a WordPress project only produced
wp-content/ + the wp-config.php bridge — ddev config never downloads
WordPress core, and even with core present the site has no database
until `wp core install` runs (confirmed live: 403/302 until fixed).
The wizard's WordPress path now chains configure -> start ->
`wp core download` -> `wp core install` as separate tracked operations
(each needs its own terminal/status lifecycle, same reasoning as the
configure->start split from the original wizard work), with new site
title/admin username/password/email fields shown only for the
WordPress project type. wp-cli requires the containers running, so
"start after creating" is bypassed (always start) for this path rather
than leaving a checkbox that could produce the exact half-built state
this fixes.

Also added, per direct request:
- Delete project: `ddev delete <name> --yes` (keeps ddev's default
  database snapshot as a safety net), confirmed via window.confirm
  with copy clarifying it only removes DDEV's registration/containers/
  database, not the project's files on disk. Clears the app's selection
  on success.
- WP Admin quick-link: for running wordpress-type projects, a header
  button opening {primary_url}/wp-admin/ directly.

Verified end-to-end against a fresh throwaway project via CDP: full
configure->start->download->install chain produced a real working
site (200 on the homepage, proper login redirect on wp-admin, WP Admin
button href matches), and delete genuinely removes the project from
`ddev list` with the confirmation copy rendering correctly. Two
apparent bugs surfaced during this testing turned out to be the test
script reading DOM state before React's re-render or before ddev's
multi-step delete (build+start+snapshot+teardown) had actually
finished — not real defects; re-verified with proper waits.
