DebtDrone v1.3: rich PDF reports, real team management, SSO fixes

Just shipped v1.3 — here's what's new:

- Report PDFs, done properly. "Download PDF" used to just be a shortcut to your browser's print dialog, which meant formatting depended on whatever browser and OS you happened to be using. It's now a real document generated on our servers — consistent, designed, and ready to share or attach to a doc regardless of what you're viewing it on.

- Team management that scales past "add people manually." You can now invite teammates by email with a specific role (owner/admin/member/viewer), or — if you're on a plan with SSO — verify ownership of your company's email domain and let anyone signing up with that domain request to join automatically. Join requests show up for an admin to approve, so you're never letting people in blind.

- SSO polish. Logging in with a work email tied to an SSO org now redirects you straight to your identity provider — no more hunting for a separate "Sign in with SSO" link. Also fixed a gap where SAML configuration could be edited by any team member instead of just owners/admins.
