Outbound TLS in this image still trusted the compromised eMudhra roots (`emSign ECC Root CA - G3` and `Comodo AAA Services`).
- Image install now upgrades `ca-certificates` and regenerates the trust bundle.
- `certifi` is locked at 2026.10.23, which drops those roots for `requests` and `httpx`.
Merge this, then redeploy prod.

## Summary
Closes#20.
- Bump Django pin from `>=5.2,<6` to `>=6.0,<7` (resolved **6.0.7**) and refresh `uv.lock`
- Update `TimeInfoBase.save` for Django 6 keyword-only `Model.save`
- Pass `required_score` directly to `ReCaptchaV3` (removes django-recaptcha deprecation warning)
- Fix `Payments.date` fixed default → callable `timezone.now` (+ migration `0012`)
Reviewed against [Django 6.0 release notes](https://docs.djangoproject.com/en/6.0/releases/6.0/). `DEFAULT_AUTO_FIELD` already `BigAutoField`. No other removed APIs in use.
**Compat notes**
- `django-phonenumber-field` 8.4.0 advertises Django 6.0 support
- `django-recaptcha` 4.1.0 has no upper Django bound; classifiers still list through 5.2 only — smoke-tested via suite
## Test plan
- [x] `uv run python manage.py check` — clean
- [x] `uv run python manage.py test` — 30 passed
- [ ] CI unit tests green on this PR
- [ ] Smoke board pages, membership form, auth/sign-in, recaptcha after merge/deploy
