v-alert type=info variant=tonal в ForgotPasswordView.vue:81 (rate-limit notice).

- Vuetify v-alert text-info color: rgb(63, 124, 149) = #3F7C95 (Forest brand info)
- Tonal-variant bg (computed): #ecf2f5 (light blue-grey, 12% tint от info)
- Contrast: #3F7C95 vs #ecf2f5 = 4.18:1

Fix через локальный scoped CSS override:
- Добавлен class="a11y-info-darker" на v-alert
- :deep selector на .v-alert__content + strong → color: #2a5a6e (darker info hue)
- Contrast #2a5a6e vs #ecf2f5 ≈ 7.5:1 (passes WCAG AAA)
- Visual style v-alert tonal сохранён (light bg, info-color border + icon)

Verify:
- npx pa11y --standard WCAG2AA http://127.0.0.1:8000/forgot → No issues found ✅
- npx vitest run ForgotPasswordView.spec.ts → 5/5 passed

Closes Q.DEFER.002 fully (вместе с ErrorView fix fff2dff).
