Shows rider count, activities imported in the last 7 days, 7-day
sync success rate, and how many riders currently need attention,
right above the rider list where an admin looks first.

Adds a self-hosted stylesheet (no CDN dependencies) with a card-based
dashboard and color-coded status badges, and shows the last 10 sync
runs per user on the detail page.
Adds full CRUD for sync users (create/list/detail/edit) behind admin
auth and CSRF protection. Passwords are encrypted at rest and never
decrypted into a template context; only emails may be decrypted for
display on the edit form. Blank password fields on edit preserve the
existing encrypted password.
