Contacts UI: address + phone inputs, search filter, address-only adds

The contacts manager in Settings was stuck at name+email inline only —
no address field, no phone input on add, no search to find anything in
a list of 100+ contacts.

UI:
- Add form gets phone and address inputs alongside name/email. The
  email-required gate becomes name-OR-email so address/phone-only
  entries are creatable.
- Edit form gets an address input, threaded into the PUT body.
- Search input above the list filters client-side by name / emails /
  phones / address (debounced 80ms). Count badge shows N/M when a
  filter is active.

Backend:
- /api/contacts/{uid} PUT now accepts address and routes it through
  _update_contact (which already supports it after the previous
  commit). Validation loosened: name OR email OR address.
- /api/contacts/add POST now accepts phone + address. Phone goes
  through an immediate _update_contact since _create_contact's
  signature only takes name+email+address.
