feat(ops/dispatch): editable tech home base + new default at Gigafibre HQ

Two changes around tech "departure point" coords (used for route
optimization when the tech has no live GPS yet):

1. New default fallback = 1867 chemin de la Rivière, Sainte-Clotilde
   (Gigafibre HQ, lng=-73.6756, lat=45.1599). Was downtown Montréal,
   which never made sense — every tech started the day with a 70 km
   imaginary commute.

2. Per-tech editable home base via a 📍 button on each row of the
   tech sidebar. Clicking it opens a dialog that accepts either:
     • a free-text address — geocoded via OpenStreetMap Nominatim
       (browser-side, sane User-Agent, no hub proxy needed)
     • or a literal "lat, lng" pair pasted directly
   On confirm: PUT to ERPNext (Dispatch Technician.latitude /
   .longitude), patch the local store row, and trigger a route
   recompute since the start point changed.

   The geocode hits Nominatim public — fine for a low-volume
   internal tool. If we ever exceed their fair-use limits, swap to
   the existing /address-search hub route which already has the
   AQ + RQA pipeline.
