Add top-level members list, primary member on account, member move, combined create flows

- GET /v1/members with search across all members (includes account name)
- POST /members/:id/move with optional accountId (creates new account if omitted)
- primary_member_id on account table, auto-set when first member added
- isMinor flag on member create (manual override when no DOB provided)
- Account search now includes member names
- New account form includes primary contact fields, auto-generates name
- Members page in sidebar with global search
