feat(fusion_claims): service-booking wizard live client search + address autocomplete

The wizard's dynamic fields were non-functional: the "Existing customer" box had
no search (no endpoint, no handler — the typed string was only sent on submit),
and address autocomplete never attached (google_address_autocomplete.js patches
FormController, which a client action is not).

Live client search:
- new jsonrpc endpoint /fusion_claims/service_booking/search_customers — searches
  res.partner (name/phone/email) and resolves a typed SO number to its partner.
- JS: debounced (250ms) onCustSearch -> .sb-cust-results dropdown; pickCustomer()
  sets state.partnerId + fills the contact, which action_book_from_wizard already
  consumes for cust_mode='existing'.
- FIELD-SAFE domain: res.partner has NO `mobile` field in Odoo 19 — referencing it
  raises ValueError and the swallowed exception made the search silently return
  nothing. Build the OR domain only over fields in Partner._fields. Smoke-tested on
  prod data ('25450'->1, '1 905-'->8).

Address autocomplete (wizard-local):
- component loads Google Places (key = ICP fusion_claims.google_maps_api_key, which
  IS configured on westin), attaches via useRef('root')+onMounted/onPatched to every
  input.sb-addr-input, writes street/city/lat/lng into reactive state. Fully guarded
  (per-input _sbAc, _addrStarted/_addrNoKey gate, .catch on both hooks) so a missing
  key degrades to manual entry and can never break render.

Verified: pyflakes clean, JS node --check, SCSS compiles, XML well-formed, dropdown
UI rendered against Bootstrap+compiled CSS. Documented in fusion_claims/CLAUDE.md §48.
Bump fusion_claims 19.0.9.6.0 -> 19.0.9.7.0.
