Subject: [PATCH] =?UTF-8?q?feat(dispatch):=20P1-C=20"Trouver=20un=20cr?=
 =?UTF-8?q?=C3=A9neau"=20=E2=80=94=20wire=20suggest-slots=20to=20a=20booki?=

The hub /dispatch/suggest-slots (gap-finding + travel buffer + proximity
ranking) existed but had NO UI (Gemini claimed SuggestSlotsDialog.vue was
coded — it did not exist). Built it:

- api/dispatch.js: suggestSlots(payload) → POST /dispatch/suggest-slots.
- SuggestSlotsDialog.vue: address (RQA geocode via useAddressSearch) +
  duration + earliest date → ranked slots (tech, date, time, travel min,
  reasons). Selecting a slot emits it.
- DispatchPage: "📅 Créneau" button in the header opens the dialog;
  onSlotSelected prefills the WO create modal (tech + date + address +
  duration) and confirmWo injects the slot's start_time + geocoded coords
  into createJob. Manual "+ WO" clears the booking slot.

Verified: dialog compiles/opens with inputs; suggest-slots returns ranked
slots (e.g. Gilles Drolet 08:15–09:45, journée libre, 15 min). Note: the
address geocode (/api/method/search_address) 403s in the dev preview
because the dev proxy doesn't inject the ERP token that prod nginx adds —
works in prod (same call the create modal already uses).
