fix(test): bump e2e birthYear 2012 → 2010 (skip parent-consent flow)

cbd74ea fixed the password-rule fixture, but the birthYear bump
2000 → 2012 introduced a new failure: 2012 is age 14, which
triggers the GDPR-K parental-consent gate (requires `parentEmail`).
Tests that don't pass `parentEmail` get 400 with
`"Konta dla osób poniżej 16 lat wymagają zgody rodzica."`.

2010 is exactly age 16 (today minus 16 years). The server check
is `< 16` (strict), so 16-year-olds bypass the parent-email
requirement while still passing my G-01 server clamp
`min(CURRENT_YEAR - 16) = 2010`.

Bumped birthYear 2012 → 2010 in all 7 e2e specs + the two
helper-fallback `?? 2012` defaults. Tests that explicitly want
to verify the parent-email flow still pass `parentEmail`
explicitly so they're unaffected.

Verified locally:
- POST /api/auth/register with birthYear 2010 returns
  `{"ok":true,"ageBucket":"16-plus","needsConsent":false}`
