Auto-sharing new events and trips with your household

By default, every new personal event or trip starts private to you — you pick the household to share it with on the create form. If your household shares most things automatically (e.g. a partner-only household), the owner can flip auto-share on so new items default to "shared".

Step-by-step (owner only):
1. Account → Household.
2. Scroll to "What you share" → "Household defaults".
3. Toggle "Auto-share new calendar events" and / or "Auto-share new trips" on.

What changes:
• The "Share with household" dropdown on the new-event drawer and the new-trip modal pre-selects this household instead of "Just me".
• Members can still override per-item by switching the dropdown back to "Just me" before saving.
• Existing events and trips are not retroactively shared. Toggle only affects newly created items.

Why per-item override stays:
A partner-only household might want to auto-share by default but keep some events private (a surprise gift planning entry, a one-off solo trip). The dropdown stays visible on every create form so opting out is one click — never hidden behind a settings menu.
