FlaskPasswordSync calls Flask's internal sync endpoint (POST /api/internal/sync-password) with a shared secret (INTERNAL_SYNC_KEY), so a password reset completed on Spring also lands on the Flask account for the same uid. Not wired up to any caller yet -- that's the OAuth-verified reset flow, next PR in the stack. Best-effort: a sync failure is logged, not fatal to whatever already-successful operation triggered it. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
New security-driven self-service reset: a student proves account ownership by signing in with their @stu.powayusd.com school Google account, and the trailing 5 digits of that (server-verified) email must match the last 5 digits of the account's stored sid before a reset is allowed. GoogleIdTokenVerifier verifies the Google Identity Services ID token server-side via Google's tokeninfo endpoint (checks aud, iss, email_verified) -- the existing signup flow only ever decoded this token client-side and never verified it, fine as a UX nicety but not acceptable as an actual security gate. POST /mvc/person/reset/oauth/verify reuses the admin/default-account guards and rate limiting from the existing email-based /reset/start flow, and on success issues a single-use token via the existing ResetCode infrastructure. POST /mvc/person/reset/oauth/complete spends that token and sets the new password, then best-effort syncs it to Flask via FlaskPasswordSync (added in the previous PR in this stack). Also invalidates JWTs when a password changes (Person.tokenVersion, bumped in PersonDetailsService.save whenever samePassword is false; JwtTokenUtil stamps and checks it), fixes ResetCode's RESET_TOKEN_SECRET resolution so it actually sees Spring's .env-imported value instead of silently signing tokens with a random per-restart key, and repoints login.html's "Forgot Password?" link at the new verified reset wizard on the pages site.

Splitting #168 into smaller, independently-reviewable PRs across spring/flask/pages. This one covers the password reset button — the core verified reset mechanism.
Depends on #169 (merge that first) — this branch includes #169's
FlaskPasswordSynccommit since GitHub can't base a PR on a branch that only exists in this fork.
