HOUSEBOT-078 Mini App Balance Breakdown

Goal

Make the mini app read like a real household statement instead of a generic dashboard shell.

Scope

• highlight the current member's own balance first
• show base due (rent + utilities) separately from the shared-purchase adjustment and final due
• keep full-household balance visibility below the personal summary
• split ledger presentation into shared purchases and utility bills
• avoid float math in UI money calculations

Notes

• no settlement logic changes in this slice
• use existing dashboard API data where possible
• prefer exact bigint formatting helpers over number math in the client
