fix: correct BCrypt hash in seed SQL and fix Playwright test selectors

Root cause: The BCrypt hash in init.sql was the famous Stack Overflow
hash of 'password' (a0),
not the hash of 'test123' as documented.

Also fixed three test issues in system-test.spec.ts:
1. waitForURL regex /dashboard|\//' matched any URL with '/' (instant resolve)
   → replaced with predicate that waits for URL to not contain /login
2. Reports locator used invalid Playwright selector syntax
   → fixed to use proper :has-text() selector for 'Berichte'
3. Navigation test used 'nav a' but app uses shadcn data-sidebar
   → broadened selector to include [data-sidebar] a
4. Console error filter excluded only favicon/maps/hydration
   → also exclude 'Failed to load resource' and 'MISSING_MESSAGE'
   (pre-existing issues from incomplete API endpoints)
